I'm preparing to upgrade the firmware of an MSA1000 controller connected using a SAN switch with two openvms alpha servers. By the book, before trying an update I should change the connections name and profile from this default configuration below:
STOR4> show connections
Connection Name: Host WWNN = 20000000-C93BB988 Host WWPN = 10000000-C93BB988 Profile Name = Default Unit Offset = 0 Controller 1 Port 1 Status = Online
Connection Name: Host WWNN = 20000000-C93BBA93 Host WWPN = 10000000-C93BBA93 Profile Name = Default Unit Offset = 0 Controller 1 Port 1 Status = Online
to a new configuration with new connection names and openvms profiles.
I plan to use this command add connection MSA-1 wwn=10000000-C93BB988 profile=OpenVMS but I just want to be sure I'm doing it right.
These two connections refer to the hba of the server, Host WWNN = 20000000-C93BB988 Host WWPN = 10000000-C93BB988 and I should use the wwpn when issuing the add connection command, right?
I refered to the MSA1000 CLI user guide and there it says OpenVMS but i'll remember this just in case.
When doing the FW update it's recommended to stop all the I/O at the MSA1000. Is there an easy way to do this? Another thing I'm worried about, what happens if something goes wrong when updating the FW, the process hangs or something like that? Is there any thing I can do after this or the MSA is just gone!
