A couple of points to remember.  UNMAP doesn't work on replicated volumes, that's either sync-replication or standard point-in-time replication.   Also depending on the filesystem, it won't immediately recover unused space on existing volumes.   Some filesystems like VMware's VMFS don't unmap on the fly, but offer a CLI utility to create large balloon files then delete and send the UNMAP commands all at once.  The basic rule is you have to have enough free space to move the selected member out of the pool.   If not, then the operation won't be allowed.  You may end up having to add that new member to the pool before you can move out an array. Side note:  If you haven't done so already, then on the Equallogic website, with the FW downloads is a document that describes how to set the disktimeout value for several OS's.   This allows the host (or guest VMs) to ride out the short outage during a firmware upgrade or a controller failover due to a failed CM.   Regards,      
Dears, We need to move a member -Member3-  to a maintenance pool for upgrading the firmware. My question is how can we calculate the needed space to move a member to another pool ? I attached some photos from SANHQ for the Group/Pool/Member capacity. [IMAGE][IMAGE][IMAGE] P.S. Consider the group space not the pool space, because we have a fourth/Demo member in the maintenance pool and we will move it to the default pool for the upgrade process only.  Regards, Turki
