Invisible replacement disk

[Peter Bosch]

sasmgr -q phy=all shows 4 disks "up"
sasmgr -q raid shows 1 logical drive (RAID-1) and 1 physical drive
ioscan shows 2 disks: 1 IR volume (the logical drive) and 1 "ordinary" disk.

I don't have exact command output readily available and to my regret I cannot logon to the system at this time. Will try to include output at the soonest available opportunity.

I would check the firmware of SAS controller and will update if it is not latest. I have seen some versions of firmware will not detect the 300GB disks.

This is the latest firmware I can find:

FW version: 1.23.42.00, EFI driver: 3.05.01.00

Make sure to have the latest driver:

My colleagues and I have thought about firmware as well but we can't explain why one disk would be visible (and available) and another identical disk would not. We couldn't explain why swapping the disks made no difference (bay 4 remains okay, no matter which disk is in there, while bay 3 won't work) either. Nevertheless, we will try to do a firmware update.

As for the requested command output, I have attached a file to this reply.

hi,

Could you just let me know which command you have used to add new disks?


I have seen only two disk in lun output, I hasn't show bay 3 disk.

The disk is obviously alive:

Info for PHY ID : 2
PHY Health : UP
Port SAS Address : 0x500605b000000002
Attached SAS Address : 0x5000c5001dd17d09
Current Link Rate : 3 Gbps
Max Link Rate : 3 Gbps



I cannot find any document about FW changes anywhere, but maybe it helps.
Did you already reset the controller?

[Peter Bosch]

It has even been powered off so I would say so. I'm planning to do the firmware upgrade tomorrow (Friday).

[Peter Bosch]

Well... the driver update was succesful but it didn't solve the problem. The firmware upgrade failed to install because of an assertion error. See attachment for details. I have logged a hardware call with HP now.

[Peter Bosch]

The firware upgrade has been implemented sucessfully - I had to use fs0: and used blk1: during the previous attempt. The problem remains, however. Will add more info as it becomes available.

We were finally able to create a 300 GB raid volume. To get there, we had to erase the headers on the disks and (under power-off conditions) physically move one of the disks of the existing 72 GB disks to bay 3. Upon starting the machine, the existing array was recognized on bay1+bay3 and we could add a new array on bay2+bay4.
