HP Lefthand OS 10.0 upgrade issue with certain management group password strings

A few weeks ago HP released the new Lefthand OS 10.0 for their StoreVirtual products. I’ve since upgraded my VSA clusters successfully,  however, when attempting this on a test P4300 cluster I ran into some weird issues.

During the upgrade (which now has a nice progress window) the first node in the cluster would upgrade OK but upon rebooting would not reconnect to the CMC. When trying to log into the direct console on the upgraded node it would not accept my Management Group (MG) password. I had no other option but to forcibly cancel the upgrade and I rebuilt the failed node.

After attempting a subsequent upgrade, the same problem occurred. This time I noticed in the status bar in the CMC that it was failing to log into the newly upgraded node and said the username and password was incorrect! As a result I logged a job with HP.

The response I received was rather interesting…as it turns out they have had several incidences similar and are related to MG passwords containing the characters ‘~‘ or ‘$‘.

So, this got me thinking…if the password is corrupted by the upgrade, what happens if I try logging in with a partial password? I tried several combinations on my test cluster until VIOLA, I could log in with the first part of the password leading up until the special character!

To clarify this, lets say our MG password was abc123$def, after the upgrade the CMC will fail to reconnect. You should be able to log into the node using abc123, i.e. we’ve dropped the $ symbol and anything after that. I’m not sure what happens if your password begins with those characters…could be interesting as the CMC does not allow a blank password!

I would imagine HP will release a patch for this in the coming weeks, in the meantime you could change your MG passwords prior to the upgrade 🙂
