"No controllers found" since OMSA 9 upgrade

Jump to solution

We've been using OMSA with CentOS 7 for many months and then a few weeks ago, OMSA upgraded on the usual overnight yum run.

Not normally an issue. We usually see SNMP monitoring fail for a few minutes during that but everything comes back.

However, this didn't happen on a number of servers of varying chassis. It's worth noting that some worked fine but others didn't (similar hardware etc).

[root@xxxx ~]# omreport storage controller
No controllers found

Machine can see the card and is running just fine.

[root@xxxx ~]# cat /proc/scsi/mptsas/4
ioc0: LSISAS1068E B3, FwRev=00192f00h, Ports=1, MaxQ=266

Drives can't be seen via OMSA interface either.

At a loss what now to try and what changed in the upgrade to cause it to break entirely.

The solution appears to be that OMSA 9 does not support mptsas so rolling back to OMSA 8 seems to work fine. I wrote about it for anyone else suffering.

Hi,

Can you private message me the service tag so we can get some additional information?

I would try to stop and restart the omsa services, if that doesn’t work try rebooting the server and if that doesn’t work try a freash install of OMSA.

Thanks,

There are multiple servers, varying chassis.

We've:

- restarted the services, stopped and then started without any change

- restarted the servers multiple times

- reinstalled

I must stress, this was working fine until yum updated to the latest release in the repo at that time and then it would not start after. Some servers were fine with identical hardware/chassis/OS but others not.

I've attempted to downgrade to OMSA 8 which was working just fine but can't find a guide on this as it just re-installs 9 each time.

No drives were pulled out.

This happened after an automatic upgrade of OMSA. Have already reinstalled multiple times.
