The button is named "restart" and initiate always a failover to the standby CM. Yes, there is no complete reboot option or task. Well... is the same "risk" of having a storage with multible heads and a couple of extension shelfs. If the storage pools or groups disk across shelfs and you loose a complete shelf you are in trouble. In theorie the risk goes up if you put more members to a pool because a volume splits over 3 volume per default. But this is a softlimit and you can adjust the volume distribution to more or less members. If you have a volume which is large and the 3 members cant deliver this capacity it can go 4 or more members. The biggest volume i ever seen spreads across 8 members.  Spreading volumes across members is how EQL scales out. If you dont like you have to disable this option or replicate your data with the SyncRep option.  Regards, Joerg
Hi, So, I'm kind of confusion about how this works.  I know I can put two arrays that are in the same group into the same pool, and I know that I can create a volume that spans the two arrays and the EQL will spread the volume equally between the two boxes, etc etc.   My question I guess is on reliability....  Am I missing something or does this seem like a "RAID 0" type thing between two EQLs?  I mean, if the volume is split between the two boxes, how do I ever do a reboot on a box?   What if one of the EQL fails?  Do I lose that whole volume?    What am I missing?   Or is this how it really works?    I'm kind of afraid of putting anything into production where a failure on one device would kill everything like that.   Any explanation would be appreciated.
