missing disk

Hi Everyone

I am having hard drive problems with a C3000 Visualize workstation. The machine has two 9.1Gb disks. One dedicated to the OS 11i and the other containing one lvol /space. When I boot up the second disk can be seen in sam but nowhere else, ie cd /space freezes.

I fear that on boot I am missing important information as to the state of the disk. Is there a boot log file on the system I can examine at my leisure?

Could anyone recomend a disk checking utility or any other way to proced in this situation other than junking the drive?

first check all connection of harddisk
reboot machine after that press STOP-A button for ok prompt
use #probe-scsi all command to detect all hard disk connected to system.
hope this will helpful for u . otherwise there may be problem in harddisk.

STOP-A makes me cringe

run "ioscan -fnC disk" command and see if the system sees the physical drive. If it is set up properly you should see the drive information displayed

Also, was the physical volume ever made active with "pvcreate"?

Hi jpetrecca

Below is the output from the command you suggest.

# ioscan -fnCdisk
Class I H/W Path Driver S/W State H/W Type Description
disk 0 10/0/14/0.0.0 sdisk CLAIMED DEVICE SAMSUNG CDRW/DVD SM-3
/dev/dsk/c0t0d0 /dev/rdsk/c0t0d0
disk 1 10/0/15/1.5.0 sdisk CLAIMED DEVICE QUANTUM Atlas4-9LVD
/dev/dsk/c3t5d0 /dev/rdsk/c3t5d0
disk 2 10/0/15/1.6.0 sdisk CLAIMED DEVICE SEAGATE ST39103LC
/dev/dsk/c3t6d0 /dev/rdsk/c3t6d0

It seems to suggest that everything is OK I think, however I still can't see lvol9 in a bdf and attempting a cd to any of the directories on that drive freezes the system.

The disk was set up in sam adding the whole disk as lvol9 to the existing vg00.

As the boot procedes I catch sight of lvol9 but I really need to access the boot log, where is this please?

Is there a chance the disk is not long dead?
