Question Itanium

[John Diaz]

LVM is supported for SAM over Itanium

[Patrick Wallek]

I'm not quite sure what you mean. Are you asking if LVM is supported on Itanium? If so, then yes.

Are you asking if you can do LVM work thru SAM on Itanium? If so, the answer is still yes.

And on SAN-attached lun's, too - in case it was a typo.

;)

Hi,

You should have provided some more information for better responses.

Still LVM part of SAM is very well supported in SAM. Still I would recommend you choose command line for LVM configuration.

The command line commands for LVM config will slightly differ in Itanium then RISC servers.


HTH,

For SAM to support LUNs on a SAN (pa-risc or Itanium), it must be a supported SAN disk array (XP, EVA, etc.) Non-HP arrays may not be handled well by SAM since SAM doesn't know about their identifier strings, and doesn't necessarily know how to reconcile the multiple paths to the same LUN. Hitachi Arrays (except for the HP branded XP) have been observed to have the issue of showing many paths for the same LUNs. There typically are four physical paths to each LUN in a SAN configuration, so if SAM isn't programmed with the correct information for that specific array, it doesn't know that they are really one LUN.
So, don't plan to use SAM with 3rd Party unsupported arrays.

[Chris Fadrowski]

that is correct. Practice using the command line when configuring disks on a SAN. You will see them using

ioscan -fnC disk

then do your pvcreate
vgcreate
lvcreate
