Raid controller 4si

[Roro_2]

Hi,
I have an RP2470 connected to external storage Disk system 2100 connected through Raid controller 4si as raid 5 ( 5 x HD ).
the disks were all flagged as FAILED with the logical drive OFFLINE, upon making them ON_LINE the logical drive status changed to degraded (actually one disk was found failed within the RAID5 logical drive)
The server was rebooted but still no disk device was detected (only the controller device) ; no device files corresponding to the logical drive.
irm, irdiag , irdisplay were showing correct information.
I wonder why a degraded logical drive is not seen by the system.

feedback are very much apprceciated

Regards,

Roger

Raid4si card ----> the most problmatic hardware I have seen and worked. data loss chances are too much.I remember that some saved configuration file is there you can re-load the configuration from there. better to take a support from HP.

Hi Awadhesh,
Thank you for your concern,
I have no problem with the configuration using Raid utility (physical/logical drive status = online) . the problem is that HPUX is not detecting the the logical drive (device file not created ).

Shalom Roger,

I think the card is dead.

If you see no disks after this, consider replacing the card.

Hi Steven,

In fact the contraller card was detected and the corresponding driver by HP-UX.
Also , the RAID utilities ( irdiag , irdisplay ) showed the configuration of the disks and the logical drives.

have you removed that failed disk drive?

Also check the Firmware level of all disks should be same.
