Hi Bill,

I'm in as a Domain Administrator - UAC is off. Checking the service account Snapdrive runs under UAC is also off.

Looking through the event logs I do see some prior events - not sure if they're related:

The flush and hold writes operation on volume F: timed out while waiting for a release writes command.

This is at 1am in the morning for each iSCSI attached LUN on the box.

Its been suggested I try this hotfix -

I'll  give it a go and let you know how I get along.

Cheers,
Raj.

Is the Admin Authentication Mode of the UAC enabled?  It can prevent access to the files in the LUN

Hi,

Simple problem - I have a SQL server (Windows 2008, 64 bit, SQL 2008,
Snapdrive 6.1 & snapmanager sql 5.0.0.38 (both 64bit)

Snapshots work fine - however the dbcc check fails when it attempts to
mount the snapshot for a verification.

Now - I am able to mount the snapshot on a Windows 2003, 32 bit box
running Snapdrive 6.1 so I'm fairly certain its not a volume space
issue.

The actual error I get is 'A timeout of 120 secs elapsed while waiting
for volume arrival notification from the operating system' - this
happens when I use the SD GUI to manually mount the snapshot. The
console shows pretty much the same sort of error if I watch it while
running the GUI mount.

We have this working fine on other SQL servers and its just started
happening on this box.

Any ideas ?

Our DBA's are starting to wonder if the aggravation of troubleshooting
SM SQL / SD issues is worth the convenience of instant snapshots. At
least with traditional backups they know where they stand.

Thanks in advance,
Raj.
