Disk Array Issue for Storageworks 2405

OS= HPUX 11.11

System= RP7420

Disk Array = Storageworks 2405 with SCIS C1010 Ultra wide 160 drives

Having issue where one drive indicates it is bad and upon replacement – we get zero disk space on the drive.

Now starting to get other disk drive errors.

Wondering if this might be a midplane issue on the disk array.

The 2 disks that are bad are not part of a volume group on system. One of the disks was a mirror disk in a volume group but lvreduced the mirrors and vgreduced it out of the volume group. Before that the vgdisplay showed some stale extents on the mirrored lvol’s but that doesn’t show up anymore since it was reduced out.

The diskinfo for the 2 bad disks showing 0 kbytes is below. They show up fine in ioscan as CLAIMED with no errors. Very puzzling. They also show up as FAILED in cstm – that output is below.

teossh1:root:/root>diskinfo /dev/rdsk/c10t9d0

SCSI describe of /dev/rdsk/c10t9d0:

vendor: HP 73.4G

product id: ST373453FC

type: direct access

size: 0 Kbytes

bytes per sector: 0

teossh1:root:/root>diskinfo /dev/rdsk/c10t1d0

SCSI describe of /dev/rdsk/c10t1d0:

vendor: HP 73.4G

product id: ST373453FC

type: direct access

The cstm output for those 2 disks:

78 1/0/4/1/0.8.0.255.0. SCSI Disk (HP73.4GST37345 Information FAILED

86 1/0/4/1/0.8.0.255.0. SCSI Disk (HP73.4GST37345 Information FAILED

No longer seeing ESM alerts in syslog. For some reason those went away.
