Can't boot from Compellent SAN

[Jim Chan_1]

We have a ES45 with KGPSA-CA running Tru64 5.1B

We are migrating our old HSG80 SAN to a SAN made by Compellent. We are able to mount a disk presented by the Compellent from within Tru64. However, when we attempt to boot from SAN on the Compellent, we cannot get it to work. Can someone help me? Thank you.

Here's what I did:
From console:
wwidmgr -clear all
wwidmgr -show wwid -full
(found item number showing the Compellent disk and used the item number in the next command)
wwidmgr -quickset -item
init
show dev
(shows the disk device dga25070.1001.0.1.1)
boot dga25070.1001.0.1.1

I get the following error:
(boot dga25070.1001.0.1.1 -flags A)
device dga25070.1001.0.1.1 no longer valid
failed to read dga25070.1001.0.1.1
bootstrap failure

Next, I tried to install Tru64 5.1B on the Compellent disk. Although the installer wrote files to the disk, when it rebooted I got the same error as above. Also of note, I got the following messages in the console box of the installer.

prom_getenv: Unable to convert 'SCSI3 1 1 0 5 0 0 0@wwid1'
prom_getenv: Unable to convert 'SCSI3 3 2 0 6 0 0 0@wwid1'

I think you'll need to solve this on the Compellent end of the fibre. It appears to be presenting the limited functionality Eprom scsi code with something it can not deal with.

As the storage guys whether they have any colors/flavors to choose from.
For example in the HSG80 you have "SET OPERATING_SYSTEM = DIGITAL_UNIX

There may well eb similar settings on teh Compellent SAN
Have them opt for the most simplistic settings for the boot disk(s)

Come to think of it, that automatically generated unit number looks might big. It is a hash from the WWID.

Just try:

wwidmgr -quickset -item -unit 200

Nothing special about 200. It's just the same sample value as used in the Manual:

Good luck,
Hein.

Apparently the Compellent has issues booting from SAN on Alphas. They say a fix will be coming on version 4.1.1 of the Compellent firmware. I guess I'll have to wait...

Thanks for the assist!
