Seems to be related to indentation on new Gen10 servers

I think the exact command run by hpsa is:

# ssacli ctrl all show detail

Strange, we definitely have this running across various configurations of Gen10 controllers and haven't seen issues. I'll take a look as time allows and see what I can find.

The message about needing to use a new version of ssacli is a new one to me, and may be worth trying out, just to see if that's causing the variation in output (needs a fix to deal with it either way, but could alleviate your problems in the short-term). Try going out and grabbing the newest version of ssacli (from wherever you're used to getting it from), and see if that helps.

[mobidyc]

I updated ssacli to the version 3.25.
and the problem disappeared.

[cathay4t]

Great. Do we need to support old ssacli also or just close this issue?

[tasleson]

My preference would be do document the minimum supported version of ssacli and close issue.

[cathay4t]

@joehandzik Which version of ssacli would you suggested to put in the man page of hpsa plugin?

[mobidyc]

I personnaly would prefer that LSM skips an unknown raid card, and continue to the other ones.

In my case ssacli returns an error when I try to access the E208i-a, but as I use only the P408i-p, in command line, there is no issue.

• I think it will be more difficult to adjust the minimum ssacli version needed each time there is a new controller.

[cathay4t]

Silently skip unknown hpsa might waste more time of user when they actually need that card managed by LSM.

I guess suggest user to upgrade their ssacli in PLUGIN_BUG error message might be better.

Included suggestion on ssacli tool upgrade when parsing error in commit 00e0048
