Resize LUN error in Storevault Manager

If you are trying to resize a LUN on your Netapp Filer and recieve the following error:

error 28: insufficient space to grow this volume with its guarantee enabled

Make sure that you have enough available space on the volume by running the df -h command. Once you have determined that you have enough space to grow your LUN then you need to run the following command, vol options ‘LUN NAME’.

Have a look at the results and check to see if you can find guarantee=volume. If you can then you will need to change this value to none by running this command vol options ‘LUN NAME’ guarantee none. Run the vol options ‘LUN NAME’ again and now you will see guarantee=none, you can now resize the LUN in Storevault Manager.

Ensure that you change the setting back to gurantee=volume by running the following command vol options ‘LUN NAME’ guarantee volume

VSS API Error Description: VSS_E_PROVIDER_VETO when using SnapManager for Exchange

If your using NetApp SnapManager for Exchange Storevault Edition and you recieve the following error,

*****BACKUP DETAIL SUMMARY*****

Backup group set #1:

Backup SG [First Storage Group] Error: VSS API Error Description: VSS_E_PROVIDER_VETO

*****BACKUP RESULT SUMMARY*****

Backup group set #1:

Backup SG [First Storage Group]: Failed

Backup failed.

Error Code: 0×80042306

VSS API Error Description: VSS_E_PROVIDER_VETO

You will need to make sure that you have enough space on the LUN that you are trying to back up.  Check your event log and see if you have an error from Snapdrive stating the following error – error code = 0×004032f,  Error description: No space left on device.  If so then you will need to do the following.

Telnet to you filer and run the following command  > df -h

This will give you a list of all your LUN’s and the amount of capicity you have left.  Look for the LUN that you’re trying to backup and see if the capacity is 100%.  If this is the case then you will need to autosize the LUN so that it can grow according to rate of change.  To do this run the following command > vol autosize ‘LUN name’ -m ‘(SIZE eg.40g)’ -i  (SIZE eg. 10g).  The command -m sets the size limit and -i sets the growth increments.  So for example if you wanted to set your LUN to grow to 100GB in increments of 10GB then the following command would be > vol autosize ‘LUN name’ -m 100g -i 10g

Here is a good article on managing data growth on a LUN.

Can not delete LUN on NetApp StoreVault Manager

If you can not delete a LUN in StoreVault Manager you will need to use the CLI to delete it.  To do this connect to the StoreVault device via SSH.  If you don’t have a SSH client download putty. Log in as root and type in the following commands.

vol status – ‘make sure you can see the LUN you want to delete”
vol offline NAMEOFLUN
vol destroy NAMEOFLUN

If you go back to StoreVault Manager and refresh the list of LUN’s, you should no longer see the LUN.
