The igroup delete command enables you to delete an existing igroup if there is no LUN mapped to it.
Syntax for this command is:
sdcli igroup delete [-m MachineName] -f StorageSystem -ig igroupName
-ig specifies the name of the igroup you want to delete.
Example
sdcli igroup delete -f 172.17.167.45 -ig v3group1fc
The preceding example deletes the igroup named v3group1fc from the storage system with the IP address 172.17.167.45.
