Hi,
The battery on one controller of our MD3000i showed up as failed recently, so I got a new one from Dell and last night, our data centre engineer installed it. The SAN has twin controllers and all the hosts are multi-path, so I simply set controller 0 offline to let the engineer do the job.
Since the controller has come back online however, it refuses to accept its preferred virtual disks back. I'm unable to ping the iSCSI interfaces from the host and although the management interface of the controller responds to a ping, SMCLI fails to connect with the message "Network errors were detected while connecting to storage array 10.x.x.x".
If I try to manually move a virtual disk back to the controller, it fails with this message:
Return code: Error 1007 - Could not communicate with the RAID controller module in slot 0 to complete this request
It appears that leaving the controller online in this state is slowing down access to the SAN from the hosts, so I'm having to leave it offline at the moment.
I'm thinking that I may have to power cycle the thing in order to get it to play ball but I'm a bit worried that it won't come back at all!
Any suggestions please?
