Hello,   Something I like to do, instead of directly deleting the member, move it to a new pool.  This will leave all the data behind,  moving the iSCSI connections to the other members as well.  Once in the temp pool, then yes select "Delete Member" and it will be reset back to factory defaults.  I would also suggest upgrading to 6.0.8 there are many improvements and with the release of 7.x firmware 5.2.x support is greatly depreciated.  Regards, 
We have a group with (2) PS5000, (1) PS6000 and (2) PS6100 arrays.  The PS5000 units are now out of warranty and we want to get our production data off these units.  (We may gen them up in the future for level 4 storage or something like that.)  The 3 remaining members do have enough storage to take over for these two out of warranty members.  I have one default storage pool.  Firmware is v5.2.8.  RAID 50. My research says I can choose Delete Member from the interface and the unit will move off its data to the three remaining members and reset itself to factory settings.  I assume, it will terminiate it's iSCSI connections as well.   Apparently there will be no loss of data with this process.(?)  I'm looking to have this research verified for me and is it really as simple as that?  Should this be done off hours?  One at a time too, most likely. Thanks for the knowledge share
