Any Help how to boot the system

[Shibin_2]

Your ioscan is not showing the device special files. Have you installed the drivers?

There is a similar thread available, but it is not for PA RISC. Hope that may help.

Btw, is it HP-UX 11.31 or 11.23? From the logs, I can see it is 11.23.

Hi Shibin,

That server was in maintainance mode when i taken the ioscan output and in maintainance mode ioscan does not show device files . Also i am very much sure i have installed the 11.31 in the server .
i am pasting the lvlnboot output which i have taken before the problem faced

# lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/disk/disk5 -- Boot Disk
Boot: lvol1 on: /dev/disk/disk5
Root: lvol3 on: /dev/disk/disk5
Swap: lvol2 on: /dev/disk/disk5
Dump: lvol2 on: /dev/disk/disk5, 0.

Meanwhile i have logged a Case with HP and they fail to boot the system and they ask to restore the system with ignite.
Let's see if anyone Can help me with this issue

>> and in maintainance mode ioscan does not show device files


I disagree. Try "insf -C".

> panic: LVM: Configuration failure

Did anything happen before the panic? Like any accidental removal of the LVM devices or disk devices?

Other than human error something must have corrupted the LVM information on the disk header.

Your vgcfgrestore came back with the c0t0d0 and c2t0d0 for the boot devices but your old lvlnboot listing shows disk5. And as pointed out above the disk5 is not in the special files list of your ioscan.
Is there something you are not telling us?

So Now According to HP there was problem with SCSI card that causes rebooting the Server and that continous rebooting of the server triggers the corruption of the VG.
We have replaced the SCSI card and for safe side we also changed the Disk and restore through IGNITE . Now Server is fine.
