Which LUN on ESS is my MPIO disk?

[unixfreak]

Well, I added a disk to a VIO server but forgot to write the LUN down and I need to de-alalocate it again. Which one was it?

Thanks

try this on VIOS:

[tt]ls -ltr /dev/hdisk*[/tt]

chances are it is the last one listed...

To make sure:

lsdev -vpd -dev hdiskXXX


Did you already turn it into a vtscsi device for a VIO client? If so, you'll need to rmdev both vtscsi and hdisk device and you'd want to make sure the VIO client doesn't have the disk open.


HTH,

login at padmin to the vio and try:
lspv -free

you will see all Disk there are not mapped to a vhostadapter, then use this command:
oem_setup_env
and look with "pcmpath query device" (if you are using SDDPCM) at your hdisk, you can see the ESS Serialnumber, the last 3 Digits are the number of the ESS Partition.

Thanks, I already knew what disk it was (also the only one that wasn't in a VG) and lsdev -vpd showed the LUN ID.

Thanks
