Booting HP-UX 11.23 server off replicated boot volume

[Roman Gudz]

We are attemping to boot our HP-UX 11.23 servers off replicated boot volumes. We are using EMC SRDF/A between two DMX2000s. The HP-UX hardware on both sides is exactly the same. We get the following messages at boot time:

System Panic:

Has anyone successfully done anything similar?

We are using VxVM for the volume manager. We split the EMC R2 volumes off before attempting to boot. The volumes visible to the servers have the exact same LUNS assigned.

Thanks, Roman

Umm, are all You're scsi and fc drivers set to be static in kernel instead of modular?

Hi,

This happend when the boot area is not updated in the disk.

though the disk has been replicated the boot area has to be updated,

mkboot and lvlnboot are MUST.

make sure the above has been done,

Regards,

Siva.

The kernel modules that I checked are set to static.

Since SRDF is a track by track copy to the remote EMC box, shouldn't the boot info be there already? I can't boot the remote servers to run the mkboot/lvlnboot commands.
