Well, the scenario is that I lost the ability to manage the storage controllers via a web browser. I could ping each controller fine, and I could also telnet into them, which is great, because with telnet you can fix this issue.
Go to Command Prompt.
Type telnet 192.168.x.x (whatever the IP is of the controller)
Enter the username and password. MSA default username and password is manage and !manage
Once you have successfully authenticated with the storage controller you can restart that controller, wait about 30 seconds before restarting the second controller, or you will loose ALL communication to the MSA, temporarily of course, although this will be enough time for iSCSI targets to most likely dismount.
Anyways, the process of restarting the controller is documented below.
HP StorageWorks MSA2012i
System Name: Uninitialized Name
System Location: Uninitialized Location
# restart mc b
During the restart process you will briefly lose communication with the specifie
d Management Controller(s).
Info: Restarting Local MC B…
Success: Command completed successfully
Once both controllers have been restarted I can pretty much guarantee that you will be able to manage the MSA once again via browser.
