mount /unmount EVA snapshots on windows 2000/2003

hi,

i'm trying to present snapshots taken on an EVA 5000 array of windows vdisks to a windows 2000 or 2003 (with secure path 4.0C sp2.1)server for backup purpose.

i started to present the snapshots, do a rescan with diskpart, and the volumes where ok to do the backup.

Now i unpresent the snapshot, do a rescan, the volume disappeared, but secure path still list the device as FAILED !!

what are the opération i need to do on the windows side to properly mount then umount the snapshots (diskpart commands ??) with secure path ???

and is still not supported to mount snapshots on a windows server with the parents lun also mounted ??


Thanx for Help !!!

Georges. An example for you using SSSU and Diskpart to dismount and delete a volume (assuming all files are in the same folder):

Create a .bat file containing the following:

diskpart.exe /s diskdel.txt >diskdel.log
timeout /t 5
sssu.exe file snapdel.txt

The above needs 2 'input' files in the same location:

1) Diskdel.txt (where 4 and z is specific to your server configuration)

select volume 4
remove letter=z
delete volume
exit

2) Snapdel.txt

select manager smaname username=administrator password=xxx
select system evaname
delete lun "\Hosts\servername\servername\lunnumber"
delete vdisk "\Virtual Disks\servername\vdiskname\ACTIVE" wait_for_completion
exit

Even using the above SecurePath will log a few errors in the event log, but this should do the trick as best as possible.
Good luck.

hi,

no way to clean up the secure path configuration without reboot !!!

it seems to be supported with MPIO !!!

BC agent seems to use an utilitie which is capable of rescaning the secure path configuration after adding or removing a lun but i have'nt found yet which one !!

steel investigate

After lot of tests it seems that it is not possible to purge the secure path devices under windows like in hpux !


So the solution is using MPIO instead, which purge it's configuration after any lun is unpresented


Thanx to all for the help.
