Getting Pool level Orphan/Unused LUNs
Hi Experts,
I know in VNX Block, we can get Raid Group level Orphan/Unused LUNs using the following command,
C:\Program Files (x86)\EMC\Navisphere CLI>NaviSECCli.exe -h ********* getunusedluns
Please share me the command by which we can get Storage Pool level Orphan/Unused LUNs for VNX Block devices.. It would be really helpful for me.. Looking for a quick positive response from you guys.
Regards
Neesha

In your question, you ask for a command to find the information about orphan/Unused LUNs and provide an example for VNX Block. Then you ask to provide the same command for VNX Block. Not sure which array you want to command for.

Hi Glen,
My command gives the orphan LUNs from Raid Group, Not from Storage Pool (which I clearly mentioned).
Please provide me the command which provide the orphan lun from storage pools in VNX.

There is no such command for pool, however, you can use some quick scripts
Example on a Linux/nas CS with naviseccli :
( naviseccli -h spa lun -list | awk '/LOGICAL UNIT NUMBER/ {print $NF} ' ; /nas/sbin/naviseccli -h spa storagegroup -list | awk '/^\W+[0-9]/ {print $NF}' ) | sort -n | uniq -c | awk '$1 < 2 {print "Unused Lun : "$NF}'
Above lists all pool luns, not in any storage group (just an idea that can be improvised)
$ ( naviseccli -h spa lun -list | awk '/LOGICAL UNIT NUMBER/ {print $NF} ' ; /nas/sbin/naviseccli -h spa storagegroup -list | awk '/^\W+[0-9]/ {print $NF}' ) | sort -n | uniq -c | awk '$1 < 2 {print "Unused Lun : "$NF}'
Unused Lun : 1
Unused Lun : 3
Unused Lun : 4
Unused Lun : 5
Unused Lun : 7
Unused Lun : 8
Unused Lun : 9
Unused Lun : 10
