An array member can only be in one pool at a time.  Creating a pool without an array member has no storage allocated until a member is added to the pool.  Volumes cannot be assigned to a pool until there is storage space in the pool. Firmware version 3.3.1 is very old and updating will require you to bring the FW up to a version in steps.  In your case you will need to do several FW updates (restarting the array in between) to get to the current versions. On the support site, you can view the required FW update path to get to the latest version (this is in the firmware update guide).  You will need to something like: v3.x to v4.0.x  then v4.0 to v4.1, then v4.1 to v4.3 then  v4.3 to v5.0 then v5.0 to v5.2 then v5.2 to v6.x A restart is required between each update.  Do both arrays to the same version first, then move onto the next version. Judging by the number of updates you need, I would suggest you give support a quick call so they can go over the steps in more detail with you. -joe
Hi Team, I have a two member iSCSI san (PS-300E's) with a default Pool spanning both arrays (total 8.7TB). I need to upgrade the firmware of each array with no disruption. There are two volumes. Vol1 (Total size: 4Tb, Used: 2.7Tb) and Vol2 (Total Size: 1.2Tb, USed: 1.1Tb) Do I simply create another pool (name it maintenance pool and configure size to bit below size of single Array = 4.2Tb) and then move the volumes into it? - allowing me to reboot other Array. Will it fail if the combined total volume size (5.2Tb) is larger than the maintenance pool size (4.2Tb), or can you migrate both volumes to the new pool if there is enough free space in the volumes. (3.8Tb 'used' is smaller than 4.2Tb) Hope this makes sense TIA
