Disk showing product id as LOGICAL VOLUME

[mjos]

Hi,
Need information on why all the disks shows product id as LOGICAL VOLUME. These disks are internal server disks & not a lun.

# model
ia64 hp server rx6600
B.11.23

The server has three internal disks.
disk 1 0/6/0/0/0/0/0/0/0/0.0.0 sdisk CLAIMED DEVICE HP LOGICAL VOLUME
/dev/dsk/c1t0d0 /dev/dsk/c1t0d0s2 /dev/rdsk/c1t0d0 /dev/rdsk/c1t0d0s2
/dev/dsk/c1t0d0s1 /dev/dsk/c1t0d0s3 /dev/rdsk/c1t0d0s1 /dev/rdsk/c1t0d0s3
disk 3 0/6/0/0/0/0/0/0/0/0.0.1 sdisk CLAIMED DEVICE HP LOGICAL VOLUME
/dev/dsk/c1t0d1 /dev/rdsk/c1t0d1
disk 2 0/7/0/0/0/0.0.0 sdisk CLAIMED DEVICE HP LOGICAL VOLUME
/dev/dsk/c5t0d0 /dev/rdsk/c5t0d0

# diskinfo /dev/rdsk/c5t0d0

[Johnson Punniyalingam]

diskinfo command does been issued under the guest ?

[Johnson Punniyalingam]

Check below diskinfo showing "product id: Virtual LvDisk "

Example :-

SCSI describe of /dev/rdsk/c0t0d0:

A rx6600 server configured for HP-UX may have a SmartArray P400 hardware RAID controller as a core storage card, depending on options chosen when ordering the server.

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

Hi,

My answer might be funny but it workes so many times for me, I think your server need a reboot........

and then check

Suraj

[mjos]

# sasmgr get_info -D /dev/sasd0 -q raid
ERROR: Unable to open the file /dev/sasd0.
Please verify the correctness of the HBA device file specified
with the -D option.

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...

[Torsten.]

No issue at all!


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!

Thanks, I can see two ciss devices.

# ioscan -fn |grep -i ciss
ext_bus 1 0/6/0/0/0/0/0/0/0/0 ciss CLAIMED INTERFACE PCIe SAS SmartArray P400 RAID Controller
/dev/ciss1
ext_bus 5 0/7/0/0/0/0 ciss CLAIMED INTERFACE PCIe SAS SmartArray P400 RAID Controller
/dev/ciss5

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?

# saconfig /dev/ciss5

The HP LOGICAL VOLUME from ioscan are the LUNs configured on the smartarrays.

You have 2 controllers, connected to all internal drives.
