LVM LUNS FC60 Array etc..

[Patrick Wirth]

I have a FC60 Array that is accessable from 3 different partitions on a superdome.

I use SAM from partition 1 to list the Disk Devices, and the volume groups that belong to this partion are labeled vg01 vg02 for lun 1 and 2 respectively. This is fine.

When I use SAM from partition 2 or 3, these two LUNS show up but the LVM column is marked unknown. Again, this is understandable since these LUNS are used by a different partition.

My dilemma is that I created LUN 3 a while ago and I'm now trying to determine if it is truly unknown, or if it is just not assigned to a partition yet.

Is there an Array Manager 60 command or a STM command that will quickly tell me what partition is controlling which LUN?

As far as the supersome stuff goes I do not know, the biggest thig I've done is a V. But I ASSUME each partition is like an individual computer & H/W, CPU memory is divided up into each partition. (i.e. you can't share a fibre channel card etc)

you can use
amdsp -i
this will show the serial number & alias (if any)
amdsp -a

mstm is slightly better, use the menu to select the array (something like A5277A Array). Use tools/info/run. This is slightly better in that it shows a diagram of which disks/luns are where in the fc60.

Also ioscan -funCdisk should give you which luns are which devices.

Putting the ioscan together with the LUN info you should be able to work out what lives where

Lastly are you fully patched up?
PHCO_23149 fc60 cummulative patch
PHSS_23655 mstm patch (A.24.00)
PHCO_23876 SAM/ObAM patch

Checked the patches... nope. Either I'm not up to date or I've got more recent patches.

Otherwise, I had already done more or less what you described and it gave me what I needed.

Thanks though.
