Firmware Update (v6.0.1) Error Messages

Hi,

While upgrading the firmware from v5.2.5/v5.2.2 to v6.0.1, I've received numerous error messages from the group.  They were:

• Connection login timed out
• Connection failed because target offline
• Free space in pool default is low. Performance on thin provisioned volumes, if any, might be temporarily decreased.
• The reported size of the volumes currently belonging to pool default exceeds the pool capacity.
• Volume state transition is in progress
• Initiator disconnected from target during login.
• The maximum in-use space limit for the volumes currently belonging to pool default exceeds the pool capacity.

Some background information: We have two PS6000 (been in production for about 2 years) and a PS6100 (just purchased and installed).  The PS6100 was going through RAID verification during the firmware upgrade and the group automatically started moving data to the new array after setup (did not know about the delay-data-move command option during RAID initialization). 

Also, the PS6000 arrays are:

• RAID 10 - 3.66 TB
• RAID 50 - 5.23 TB

And the PS6100 array is: RAID 50 - 48.3 TB

The process in which I took to upgrade the firmware was the PS6100 first, then the RAID 50 PS6000, and finally the RAID 10 PS6000.  Also, SAN HQ would disconnect me from the group.  Group Manager GUI was also extremely slow to show me information about the group, member, just about everything.

While I have completed quite a few firmware upgrades in the past, this was the first time the Equallogic group sent this many error messages.  I thought during array restart, the array would still be fine since it upgrades the secondary controller first, fails over to the secondary controller, and updates the ex-primary controller which should not have the arrays "screaming" at me. 

Can someone please tell me what I'm doing wrong to keep the Equallogic group from yelling at me?

Thank you
