Hi Everyone,
I have hp Integrity rx2620 server,with hp-ux installed on it. The server went down,I tried to troubleshoot it , now the server can boot to hp-unix only if I swap the Hard drive on bay 2 on the drive controller cage but when I use put the Hard drive to bay 0 or bay1 the server does not boot I change the drive controller board but still going through the same problem. any help????

So are you actually going to tell us what error message you get on the console during boot when the drive is in the other bays, or do you want us to guess?

This is not clear to me ...

"The server went down" - Why?

"can boot to hp-unix only if I swap the Hard drive on bay 2"

Where was the disk before?

Any devices connected to the external SCSI port?

Any smartarray controller in use?

[Coulibaly Mamadou]

If the drive is on bay1 or bay1 It will give the error saying '' hp smart array 0 logical drive found and scsi card not configured'' And It will not go further.can this be the Firmware problem?

[Torsten.]

OK, you have a smartarray card installed.

This is really different to systems not having this card.

What slot/bay is the "default" location of your boot disk?

Some more information:

In the default config *without* a smartarray the lower 2 disks are connect to an internal SCSI controller

disk 1 0/1/1/0.0.0 sdisk
disk 2 0/1/1/0.1.0 sdisk

and the upper drive to another

disk 3 0/1/1/1.2.0 sdisk


With an SA640x you can either connect the 2 lower disk drives to one channel and let the upper disk stay on the "normal" controller or
connect the upper disk to the other channel (this doesn't really make sense, unless you want to have a spare drive).

If your upper disk is connected to the default controller, you cannot put it into another slot, because the RAID controller cannot access the data on this drive and vice versa.

Wht i have understood from this scenario is that, the Smart array cards is not seeing the two disks in in the lower bay. It can't create a logical volume. I guess that the smart array firmware should be updated.
