sdcli error

Hi all,

When I run the following command -

C:\Program Files\NetApp\SnapDrive\sdcli.exe snap mount -r
mosssqlp1 -k F -s sqlsnap__mosssqlp1__recent -d Q

I get the following error -

Initializing...Unable to connect to the virtual disk in snapshot.
Error : Not enough storage is available to complete this operation.

Which is quite different from -

Error description: No space left on device.

Which is what I get on a full volume - so its completely
understandable. The 'Error : Not enough storage is available to
complete this operation' would appear to be a red-herring (ie nothing
to do with storage or the SAN per se but some oddball way of Windows
2003 telling me theres some other problem.

The annoying error seems to indicate a possible rpc problem in Windows
rather than with SnapDrive itself. The same script on the same machine
will happily mount snaps from other machines for backup purposes and I
can't really pinpoint why its not mounting these snaps. If it does
turn out to be an rpc issue could it be that the domain account on the
server under which SnapDrive runs cannot be validated on this box ?

I still haven't got my head around how sdcli talks to the SAN - if I
have a backup server mounting snapshots of luns being used on other
systems does it need to be able to talk to the system using the luns -
why can't it deal direct with the SAN ?

Thanks in advance for any tips or toubleshooting suggestions.

Cheers,
Raj.

To see what happens here, it might be an idea to do what snapdrive does for
you, but then on the ONTAP cli, being:

1) Create a snapshot backed lun: lun create -b <snap>> <newlunname> IIRC
2) Check if an igroup is available that contains just your one system. If
not, create it.
3) Map the lun to the needed igroup

If that all happens on the CLI without any problems, you just have excluded
the volume as a possible source of the problems ... :)

My suspicion is that you have no available space in your volume due to
flexible reservations being high enough to reserve all free space.

Kind regards,

Nils

When in doubt reboot - fixed the issue.

The system was dual homed (nic on the SAN network and a nic on the
Data network) - suspect the nics got confused when they came up and
started misdirecting rpc traffic.

Cheers,
Raj.
