SLES11SP2 core recognition to the hard drive, but can not be

SUSE Linux Enterprise Server SLES Configure-Administer

I passed the store to SLES11SP2 system added a “Lun”.
By “cat / proc / paration” to see the “lun” called “sddlmaf”, but use “fdisk-l” Take not see partition.
Use “partprobe” can not synchronize the kernel partition information to the partition table.
Reboot the system does not work too.

cat /proc/paration

251 80 104857920 sddlmaf
251 96 104857920 sddlmag
251 97 88413727 sddlmag1

Hi andyleigood,

your question is a bit hard to read, so I had to assume a few things:

I believe you meant to write “/proc/partitions”. That file has entries for complete disk devices, as well as partitions on such devices.

Since you cannot see any partitions in /proc/partitions for sddlmaf (well, at least I can only see the full disk device entry), and “fdisk -l” doesn’t show any either, the disk will probably be simply unpartitioned. Did you create any partitions on that LUN?

BTW, your quote of “cat /proc/partitions” seems incomplete, not only because of the typo: I can see two partition entries, sddlmae1 and sddlmag1. But only for sddlmag1 the full disk device is listed (sddlmag), while sddlmae is missing.

Have you tried “fdisk -l /dev/sddlmaf” to see if any useful details are reported? What happens if you create partitions on that device, are these persisted?

Regards,
Jens

Use “fdisk -l /dev/sddlmaf” command,system show “Cannot found /dev/sddlmaf,is not a directory or parations.”

hm, that’s strange. I have’nt hat to deal with that HSD software yet, but all references list /dev as the path where the device file is put… have you searched for other occurrences under /dev?

Jens

Thank you Jens.

Hi andyleigood,

were you able to resolve this issue? If so, it might help future readers of this thread to learn what had to be done.
