Pci SmartArray P400 raid, add disks and rebuild

[tomas didie]

Hello, I have following problem.
I am using RAID1 over two disks now we get 6 more disks and I wold like to build RAID5, so I want to add disks to current RAID1 and then rebuild it to RAID5.
But I got this error message when I want to add disks:

./saconfig /dev/ciss2 -E 0 -p 1I:1:11 -p 1I:1:12

saconfig (/dev/ciss2): Error - FW command bad status (CHANGE_CONFIGURATION)
saconfig (/dev/ciss2): One or more fields in command have invalid data, cmd_status=4
saconfig (/dev/ciss2): Current driver state is READY

sautil /dev/ciss2

togeather with HP I found a solution, in my case it's

1. Create temporarily a logical drive with the new disks:

Example: saconfig /dev/ciss2 -R 1 -p 1I:1:11 -p 1I:1:12

> 2. Delete the new logical drive (where 1 is the of the new created logical drive):

Example: saconfig /dev/ciss2 -D 1

3. Extend the existing logical drive with the new disks (where 0 is the of the existing logical drive):

Example: saconfig /dev/ciss2 -E 0 -p 1I:1:11 -p 1I:1:12

Cause:

This error occurs because the new disks were used before in a non-raid configuration.
NOTE: This procedure also works for two disks and more.

HP is aware of this issue. A final fix for this may come with a future driver or firmware.
