Re: Disk showing product id as LOGICAL VOLUME
A SmartArray RAID controller will hide the actual physical disks from the OS, and present only the logical disks specified in the RAID configuration. Only the SmartArray management tools will see the actual physical disks.
I haven't seen a rx6600 with a SmartArray running a HP-UX, but I would expect it to look exactly like your situation.
Please check out the sasmgr command:
http://docs.hp.com/en/B3921-60631/sasmgr.1M.html
For example, run this (or similar) command to get more information on your disks:
sasmgr get_info -D /dev/sasd0 -q raid
MK

ERROR: Unable to open the file /dev/sasd0.
Please verify the correctness of the HBA device file specified

I have logged in using root account.
Not sure whetehr restart will sovle the issue, but can try out that option also.
Any other clues...

Re: Disk showing product id as LOGICAL VOLUME
Your disks are connected to a smartarray RAID controller.
Perform "ioscan -fn" and look for a "ciss" device.
Then use saconfig/sautil to get more information.
Example:
# saconfig /dev/ciss5
Your server is using a hardware RAID and cannot see individual disks!
Hope this helps!
Regards
Torsten.

In saconfig, I can see there are 8 - 146 gb physical drives. What does logical drive indicate here. Does the logical drive here point the ioscan -funC disk ouput where it shows three logical disks?

Re: Disk showing product id as LOGICAL VOLUME
You have 2 controllers, connected to all internal drives.
Hope this helps!
