Is it possible to Ignite a SAN volume group?

That's the question. Is it possible to create an Ignite archive of a vg00 that's actually on a SAN rather than an internal disk?

I ask this because I ran make_net_recovery on a machine that has vg00 on the internal disk. The archive was created successfully but the last few lines of the logfile were:

diskinfo failed for device /dev/rdsk/cXYZ
diskinfo failed for device /dev/rdsk/cABC
.......

and these disk devices are SAN volume groups.

Why was Ignite bothering with them anyway? I specified "-x inc_entire=vg00" in the make_net_recovery command.

thanks

hi

yes it is always possible if ur VG vg00 disks are local or are in SAN.

the other thing that the message that u get is that the Ignite tries to check the other VG Disks also.

Ignite always does a vgcfgbackup of all the VG available
also it does diskinfo for all the disk

chck if diskinfo command works on the above disk

If not, analyse it why.. ioscan show NO_HW etc

Also I hope you are running the latest ignite version

Shalom,

Its not a great idea to boot an HP-UX server off a SAN, which is in essence what you are proposing. This approach limits your options for diagnosis should boot fail.

The Ignite command you are wanting to run is perfectly valid. If vg00 is on a san and the system is booted off HP-UX, you can use this option. Ignite could care less where the disks are.

The focus here should be trying to figure out why these disks are not responsive. Its not strictly an Ignite issue.
