Solved!
Go to SolutionStorage Reclaim
one of the host is been decommission for a clariion array, I just want make sure I go with correct procedure.
1) Remove the host from the SG
2) Remove the Luns
3) Unbind all the Luns
4) Delete the SG
5) Deregister the host from the clariion as they do not have anymore storage on the box.
the host is a solaris Host.
will there be any Impact on host if we do this when the host is running, storage is given from other clarrions.
Can we follow this same for Windows also if its running.

Hulk,
do NOT stop or restart PowerPath service on a system if it's using EMC storage from another array.671

never tried it in that sequence ..i always de-register after zones have been dropped. That way it's much easier to identify correct entries to de-register as they will turn "washed out" color and will say "No" in the Logged-in column in connectivity status.671

just a wired Question?
What if remove the host details at first /etc/Navisphere/agent.config and restarted the agent so the de-registering part is skipped.
Can we do this.. like a short cut....671

even if you stop Agent on the host, you will still need to deregister the host on the array - Agent will register the array, but will not deregister.

# /etc/init.d/agent stop
# /etc/init.d/agent start
If you are using Emulex or Qlogic cards and utilizing persistent binding you will need to go into lpfc.conf/qla.conf as well as sd.conf and remove entries for array being disconnected from this host. You should be able to do all this online ..carefully
Windows is much easier, remove appropriate drive letter in Disk Management. Step 1-4, before step 5 modify agent.config file and remove entries for Clariion being disconnected, restart agent. Remove zones and run powermt check (remove dead paths/devices) and powermt save.
