Partitions not recognized at boot

Hello,

I've a DL380G5 with MSA500G2 (including redundant controller) and an installed SLES9P3. On the MSA I have created one logical drive (RAID 1+0). In this logical array I have created two partitions (see attached fdisk-output).

But I can't access the partitions. They aren't recognized while booting (all other partitions from the node are shown in dmesg, but not from the MSA). Also the partition are not listed in /proc/partitions and not under /sys/block/cciss (see attached directory listing).

If I boot from an old rescue CD, I can't use these partitions, so I guess this is an issue with SLES9. BTW: I installed the systems from an image, with is running on 6 other DL380 systems without problems ...).

The hardware runs with the latest firmware and I have installed the latest cciss driver from the HP driver page.

What can that be?

Thanks
Joerg

Hello,

I forgot:

echo 'rescan' > /proc/driver/cciss/cciss2

does't solve the problem.

Thanks

Re: Partitions not recognized at boot

sorry, but I am a little confused. You say you can't see the partitions, but you provide info from fdisk. What am I missing? Can this machine see the disks?
"The difference between me and you? I will read the man page." and "Respect the hat." and "You could just do a search on ITRC, you don't need to start a thread on a topic that's been answered 100 times already." Oh, and "What. no points???"

Hello,

yes, the machine can see the disks. If I perform the command "partprobe" on the disk devices, all the partitions are recognized and the normal entries are inserted under /sys/block/cciss. Now I can work with the partitions as expected.

But this is not the normal way...

Thanks,

Shalom,

What kind of HBA cards? QLOGIC?

Either way you may solve this problem by building a new ram disk image

mkinitrd

Hello,

there are Smart Array 642 Controller in use.

mkinitrd: already done, because I have installed the latest cciss driver.

Thanks,
