Filer General

Messages at screen is configured at

/etc/syslog.conf.sample

By default, there is no such file, but if user modifies this file, they will have

/etc/syslog.conf ----------- which will tell where to direct messages at screen ( typically /etc/messages )

Sysconfig –t ( tape information )

Source –v /etc/rc - this command reads and executes any file containing filer commands line by line

autosupport.support.url < url address must be reachable >

Autosupport troubleshooting

1. ping netapp.com from filer2. TCP 443 SSL should be open at SMTP server

SMTP server may stay in DMZ side

3. Mail relay in exchange must be specified. Filer’s host name or IP address must be specified in mail relay. Routing for netapp.com or routing by this host or routing by this ip must be enabled for filer. Filer is acting as a SMTP client. In general setup of mail system, no SMTP client is able to send the mail thru mail server to other SMTP server when host’s identity is different as far as mail id is concerned. Relaying is blocked generally.

4. Proxy server http / https must pass http url

In 940s – NVRAM5 is used as Cluster interconnect card as well, “two in one” on slot 11

Time Deamond

(port 123, 13, 37 must be open)

When there is large skew, lot of messages from

CfTimeDaemon : displacements /skews:10/3670,10/3670, 11/3670

Because of this hourly snapshot creation also fails or in progress message appears.

Because of timed.max_skew set to 30 min, we may see above message in every 30min- 1 hr

If we set this to 5s and see how skew happening – if we see lot of skew messages (once we turned ON to timed.log ON ), MB replacement may require.

For temporary do

Cf.timed.enable ON on both cluster filers and watch those off errors

Checking from unix host

# ntptrace –v filername

From filer check

Filer>options timed

( check all the options of this )

From filer view => set date and time : Synchronize now < ip of NTP server > => do synchronize now and check NTP from unix host.

Tip : if there are multiple interfaces in filer, make sure that they are properly listed in NIS or DNS server – same host name , multiple ip addresses may require

BPS ( Blocks Per Sector ) of Disk

Block Append Checksum requires each disk drive to format it to 520 or 512 BPS per sector This provides a total of 4160 bytes in 8 sectors. This space is broken into two parts. First part is 4096 bytes ( 4K - the WAFL file size ) of file system data. The remaining 64 bytes contain the checksum data for previous 4096 bytes. In this manner, the checksum block is appeneded to each block of data.

First two numbers FSID

Next three : FID, Inode, FID

Next three : FID export point

Now, inode is different for different volume

It is found by

• priv set diago vol read_fsid vol0

=> gives hex number – should match any number above so that it indicates, file of which volume has problem. Hex number can be converted to decimal value as well

In unix side

# find –inum <decimal value >

# find /mnt/cleearcase –inum _________

( checking FID for above mount point )

# /etc/mnttab

( look here to find that number as well )

# ls – li prints inode numbers – in decimal – convert that to hex

# find . –inum < number > print

( Sometimes, vol fsid number found must be reversed to get the exact place of innode )

General Permission Problems

Check the export permissions

Check the local unix system – file level and owner level Permission and also qtreee security

( Sometimes filer permission comes to stay on top of local permission at unix box, so that it cannot be seen – they will become hidden )

To find use

# chmod

#chown

Read unix files

• # cat• # more• # vi

Net view \\filername should show all shares from windows side and cifs shares should show from filer side

But, when share is accessed from windows machine, we get No Network Provider Present. Ping works, iscsi works, iscsi drives are OK – can access. But, cifs shares does not work. In filer side we see ‘Called name not present ( 0x82). Cifs resetdc also gives the same message.

Check :

1. If filer and windowsdc is rebooted at the same time because of power failure this is seen. Filer needs to come first and then DC

2. make sure that there is no virus related activities goin on that host. Virus scan to windows host or filer can also make this happen

When trust is there

When trust is newly established – No Logon Server available may come while accessing.

Cifs resetdc will make it work. Also in some permission issues.

Wafl.net_admin_priv_map_to_root ON*

Options cifs.trace_login ON

* to take ownership of file by windows top level administrator when file is created from unix side and has only unix ACLs

CIFS + NFS both

Scenario A

1. qtree in vol is created with mixed sec2. share that qtree3. groupwise users access in unix are defined in /etc/group file

/etc/group - > is in unix side. Client or NIS server Eng::gid:khanna, Uddhav

In client side

ls –l file / directory listing chmod chgroup chown

( to see both permission in cifs shares – permission from unix and permission from windows use secureshare access )

4. In windows create group and give access5. . /etc/usermap.cfg file is used to map user accounts in windows and their corresponding

account in unix to access/manage resourcesWin unix- <= - (unix to windows)- >= - (windows to unix)- == - (both)Test\* == - ( all users of test windows domain)Domain\<user> => root( if the user is not able to see home directory but all other users folders ; CIFS restart and access home )

6. when file is created in that cifs directory or nfs mounted place, the ownership is maintained by who ever created it and access is granted by usermap.cfg file

7. Make sure that Wafl.net_admin_priv_map_to_root ON( sometimes permissions are locked and some files gets corrupted; while accessing it says do not have access or encrypted. Every other files works fine. In this case changing

Options cifs.nfs_root_ignore_acl from off to ON and Change the permission from NFS mounted side –unix to Chmod 777 and access file. Change back to OFF. Will work after this all the time

(this was the cause when user upgraded from 6.4 to 6.5 and some files in mixed qtree’s folders were not able to access nor change the permission from even root user from NFS side. Above permission reset made it work.

Scenario B

1. qtree is created its security is unix2. share is created of that qtree – so location is the same3. cifs client cannot chdir into directory if the user has execute4. Permission – d-wx-wx-wx eg MODE == 111. User gets

NT_Status_access_Denied message when accessed5. If the user is granted read only – MODE == 444 ), chdir is

Breaking snapmirror

1. snapmirror quiesce < destination path> #--- check from Snapmirror.conf file2. snapmirror off3. snapmirror break < destination path>

To Resume the operation

Have to resync

snapmirror store #initialize a volume sanpmirror from tape on source vol

snapmirror retrieve # on mirror vol

Synchronous Snapmirror

• /etc/snapmirror.conf• filera:/vol1 filerb:/vol2 - sync• #multi path• src_con = multi()• src_con:/vol1 dest:/vol2 - sync• #src_con = failover()

Steps to create Mirror

1. Enter the license on both2. user snapmirror.access option to specify the destination filer3. on the destination filer , edit /etc/snapmirror.conf file

4. On both source and destination filers enter snapmirror on command5. on the destination filer, run snapmirror initialize <destination > command

Requirement

• Destination vol must be restricted• Everything in destination will get deleted once initiazlied

snapmirror optimization

filer > options snapmirror.window_size 199475234 (default ) (this will cause large brust of packet – does not work well for WAN. May cause large packet drops resulting in the termination of snapmirror transfer or resulting very low throughput )

To change this

Dest filer > options snapmirror.window_size < between 8760 ~ 199475234 )

Window size calculation

Window size = roundtrip delay * desired delay

Eg: for 10 mbps and RTD 100 millisec

(100/1000)*10,000,000 /8 = 125,000

Options snapmirror.delayed_acks.enable off

Snapmirror problem

On the source filer

Snapmirror source transfer from <vol> to <destination filer>:<vol. : request denied, previous request still pending

Socket connect error : resource temporarily unavailable

Sol : On Destination

1. make sure that vol is there2. other source is pingable

Snapvault troubleshooting

Ifa backup relationship from OSSV is created and then deleted from secondary, any attempt to recreate it fails with error message:

“Transfer aborted: the qtreee is not the source for the snapmirror destination”

Example

Twain*> snapvault start –s fsr-pc1:E:\smalldir /vol/tinysmalldir

( error at console : snapvault : destination transfer from fsr-pc1:E:\smalldir to /vol/tiny/smalldir : the qtree is not the source for the snapmirror destination

Transfer aborted : the qtree is not the source for the snapmirror destination

On the primary log : error : E:\smalldir twain:/vol/tiny/smalldir Invalid qtree/snapshot requested

Log: e:\smalldir twain:/vol/tiny/smalldir unexpected close getting qsm data

To workaround

Release the relationship on primary using

• snapvault.exe release e:\smalldir twain:/vol/tiny/smalldir

To see what relationships are releasable type

b. While DFM is downloaded and installedPrimary storage system Primary System Name NDMP user < root > , if no other users are defined NDMP p/w < >

c. Telnet to port 10,000 and make sure that it can talk and not blocked.

Diagnosis between DFM host and Filer

At host where DFM is downloaded

• C:\> dfm host diag < primary filer >

• C:\> dfm database get dbDir c:/Program files/Network Appliance/Data Fabric Manager/DFM/Data dblogDir dbCacheSize

Snaplock

• vol create src1 –l 2 (at this point question is asked , read that carefully, this volume cannot be deleted. It is one time)

• vol create dst1 2

• vol status ( you will see snaplock compliance vol here )

• snapmirror initialize –S giardia:src1 –L giadia:dst1

VIF

Create steps

a) vif create vif1 e0 e7a e6b e8 --------single mode

OR

Vif create multi vif0 e4 e10 ---- multi mode

b) ifconfig vif1 < ip of vif > netmask 255.255.255.0 mediatype 100tx -fd

c) update /etc/rc filed) reboot

Tip 1

• check filer > routed status• filer > routed ON

Tip 2

If there is 3 port ( eg : 2 Gig and 1 100 bast T Ethernet ) so that e0 ( default – 100 base T ) – e0 must be turned off

Vfiler

If the hosting filer administrator does not have CIFS or NFS access to the data contained in V filers, except for that in Vfiler0. After storage unit is assigned to a Vfiler, the hosting filer administrator loses access ot htat storage unit. The Vfiler administration gains access to the Vfiler by rsh to the Vfiler’s IP address.

As hosting filer administrator, before you create a Vfiler with the /vol/vol1 volume, you can configure the /etc/exports file so that you can mount the /vol/vol1 volume. After you create the Vfiler, an attempt to mount the /vol/vol1 volume would result in the Stale NFS file handle” error message. The Vfiler administrator can then edit the Vfiler’s /etc/exports file to export /vol/vol1, run the exportfs-a command on the Vfiler, tehn mount /vol/vol1, if allowed.

• >ipspace create vfiler1-ipspace• >ipspace assign vfiler1 e3a• >ifconfig e3a 0.0.0.0• >ipspace destroy e3a_ipsapce• >ipspace list• >vfiler create vfiler2 -s vfiler2 -i 10.41.66.132 /vol/vfiler/vfiler2• >vfiler status -a• >vfiler status -r #running• >vfiler run vfiler1 setup• >vfiler stop|start|destroy

does it need to be started after setup?

VFM

Cache location

C:\documents and settings \ all users\application data\nuview\storage\server\cache

To change the location of the VFM application directory

<C:\Documents and Settings\All Users\Application Data\NuView\>, which contains the cache directory:

1. Take a snapshot of the application in case there is a need to return to the working state. This can be done through VFM in the Tools menu by selecting Take Application Snapshot Now. Have the user create a snapshot and save it.

2. Save a copy of the VFM application folder < C:\Documents and Settings\All Users\Application Data\NuView> somewhere for backup purposes.

3. Exit VFM and stop the StorageXReplicationAgent service and the StorageXServer service. 4. Create a folder on a different drive on the VFM server where the application directory should reside in the future. Please use a

local destination for the folder for example D:\VFMAppData. A mapped drive does not work in this situation. Create a new subdirectory called NuView in the new location. Ex: D:\VFMAppData\NuView

5. Go to the C:\Documents and Settings\All Users\Application Data\NuView directory and copy the StorageX directory to the new location created by the user under the NuView subdirectory. The new location should look something like this: D:\VFMAppData\NuView\StorageX

6. Open the registry with regedit.exe and find the HKEY_LOCAL_MACHINE\SOFTWARE\NuView\StorageX key. Add a new String Value here with the name AppDataDir and set the value data to the root of the new cache location. Ex: D:\VFMAppData

7. Close regedit and start the StorageX Server and Replication Agent services. 8. Start VFM and wait as it reads through the new cache directory and loads roots and information that were copied to the new

location.

Bakup media fundamentals

Ndmpd should be ON

To check

• Filer> ndmpd status• Filer> ndmp probe 0 [ session 0 , can be from 0 – 5 ]• sysconfig –t ( will give some backup media information )• mt –f nrst0a status• restore tf nrst0a # – display file list, there can be multiple backups in backup file,

which is filelist• mt –f nrst0a fsf 1

• storage disable adapter <port>• storage enable adapter <port>• storage show tape supported - should show wwn if yes• (sysconfig –a – will tell port and also shows if adapter card online or offline –

usually slot 10)• /etc/log/backup ----- log files

List all the files in backup

• Filer> restore tf rst0a rewind (rewind the tape)• Filer> mt –f rst0a fsf 6 (move the head to file list6)• Filer> mt –f rst0a status ( make sure )• Filer> restore –xvbfDH 60 rst0a /vol/vol0/… ( restore )

Testing

dump 0f rst0a /vol/vol0/etc/usermap.cfg ----- example

SCSI tape diagnostics to send vendor ( more detail messages )

• Filer> mt –f diag 1 -------- ON• Filer > mt –f diag 0 -------------- OFF

Copy & paste console messages and send to vendor

( with diag 1 – ON, all the messages will go to etc/messages like when any backup job, command is executed like mt –f, rewind, offline , erase, status diag etc )

Some issues

a. If veritas is showing RED to LTO tape devices, then reboot LTO and restart veritas servicesb. If backup is done from Veritas software, make sure that no sessions are staying back as cifs share sessions. Go to my

computer->Manage->connect to filer->shares->sessions.

Administrative shares of backups are seen here as sticking – not going away even after backup is complete and you see huge list here.

1,2 are incremental copy ( cannot go beyond 2 though )

NDMP copy from Vol to Vol ( /etc/hosts.eqiv file must have two filers information – their entries )

( best solution for data migration ; snapmirror or vol copy will cause fragmentation - filer will retain ACLs )

a) Ndmpcopy source:path_to_vol destination:path_to_volume -level 0 –dpassFor data changed since level1

b) ndmpcopy source:path_to_vol destination:path_to_vol –level1 –dpassFinally turn off cifs and nfs : for final incremental backup

c) ndmpcopy source:path_to_vol destination:path_to_vol –level9 -dpass

( After this level 0 is done, a level 1 ndmpcopy may be done to copy the data has changed since level 1 )

Data Migration

• Ndmpcopy /vol/vol0trad /vol/vol0

• Vol options /vol/vol0 root( this will also automatically set the aggregate option to root upon next reboot )

Tip:

If wrongly copied to vol – sometimes, we see vol inside vol0 and vol cannot be deleted. When accessed by \\filer\C$ - we see vol and that cannot be deleted. It says folders lost or not found. In that case, the folder can be deleted. Renaming possible, rename it and delete it.

Due to Overlapping of SME backup and snapshot

Scheduling timings. In SME , sme verification process (

7or 8’th process also fails) kb2370

Exchange Restore

1. Up to the minute – what ever have since last crash, will replay the log files automatically so database is up-to the minutes. Test back and restore, will have fundamentally no effect. If backup is done and mail is deleted, and restored instantly, the intermittent log files will be deleted and hence no effect. Basically it was within the database, so system take as it already exists and ignore, but will have all latest mail

2. Point in time – till that time ; all the backup after that date and time is not usable. Cannot get mails after that ; logs are deleted.

While restoring to Recovery Storage Group

1. Mount the previous SME shapshots – both database and log files2. copy those to recovery storage group directory3. if tried to restore – will get exchange error : C1041739 error4. Copy eseutil.exe files to that directory – files are

Eseutil.exe Ese.dll Exchmem.dll Exosal.dll Jcb.dll

5. run eseutil /mh pirv1.edb Eseutil /p pirv1.edb

6. Restore, during that time system ask to overwrite the database files, it is the option at the bottom of database properties, choose that option and restore

7. System is monted.

Verification failure example

Local error code : 0xC004031d Event ID 209 also event id 264 - job failed

Remote Verification RPC server unavailable – 0xC004146e

Event ID : 177

Sol : Local server has preferred address set to dedicatedly connected cable. Local server has one nic for filer iscsi connection and other nic for public. Filer had two nics – one for dedicated iscsi connection ( 192.168.1.1) and the other 10.1.8.11 for cifs and other connections. From remote change preferred ip to 10.1.8.11 ( the other ip of filer ). Make sure that at least drives can be created from this verification server. After preferred ip address change no above error happened.

The main problem of RPC was not able to ping from private network to public network. If remote verification is doing from another server, it is advisable to not to make iscsi session to the same nic where Local ( source ) server is talking. It gives RPC error – error code 0xC004146e with event ID 250 and Event ID 117.
