Kernel panic after adding disk

DD-CC — Fri, 02 Mar 2001 11:06:52 GMT

Hi there

I'm having problem adding a extra diskarray (A3311A) with 6 new disks to my K220 server running hpux 10.20 on the F/W SCSI. After trying to load the vmunix kernel the kernel panics and the system crashes.
The last thing before the kernel panics was something about scsi id 10/8.7.0, but - I can't recall the message from memory.

I want to add 4 disks on scsi id 10/8.9.0, 10/8.10.0, 10/8.11.0 and 10/8.13.0 and 2 disks on 10/0.9.0 and 10/0.11.0.
I've checkt the scsi id settings on an other server by scanning the scsi bus and the addresses are setup correct. I've also checked the cables and they are ok.

Output from ioscan:

Hi ,

Please colect /var/adm/crash and sending to HP Solution Center for analyze.
Or please try install scsi and LVM patches.

Hi,

Can you please let me know whether the disk array which you are trying to install on your server is connected externally/internally through a same cable or different one with I/O card?

Please let me know.

Hi,

I mean to ask that whether all the disks of the disk array are physically connected to same I/O card or different I/O cards.I mean to ask how they are oganized and physically connected.

Please reply

Hi,

If the disks are sharing the same cable and and connected to only one I/O card than I think that what you are trying will not work.

If setup is different than what I visualise please ignore the message.

Good luck.

Hi, and thanks for the reply

As Tim pointed out this question is also posted under the storage forum, but due to lack of answers (at that time) and impatience I posted it here as well.

The diskarray is an externally rack, and I'm trying to connect 4 disks to F/W scsi I/O on hw address 10/0 and 2 disks on F/W scsi I/O on hw address 10/8 - with two different sets of cables.

When I interact with the bootprocess and do a 'search' for bootable devices all new disks are displayed.

Now, the server is (of cause) an important server so I can't get my hands on it again for at least an other week. At that time I'll try the ODE tool to scan the scsi to see what's on the bus and test the disks.

The diskarray I'm using was running fine on an other server a couple of days ago, so it should be ok. If ODE dosen't show any errors, I'll try anyway to connect the diskarray without disks and boot the server, and then plug in disk by disk (and rebootding each time) to find the sinner-disk.

... or should I try something else ?
