MSA2012fc problem. Drive link down, Disk channel error

billydump — Thu, 09 May 2013 08:46:13 GMT

Dear all,

Could you please help me identify the problem with the msa2012fc storage system.

The system hanged blocking the access to data, failing 3 out of 6 hdds in a raid6 array. The first error logged in the event log related to the failure is A193790 Drive link down Chan0.

After this the controllers were down, was unable to connect through SMU. Had to reboot the system, after some time the system recovered and the drives/volumes seem ok, but the would like to understand the cause of this, and ways to prevent this occuring again.

Thank you.

Hi,

In event log check the past events, typically Event code 58 is for drive errors. I would recommend replacement of the drives if there is any errors.

here's the link to event description guide,

Hi,

Thanks for the reply. Unfortunately the log is somehow truncated, or cannot go back that much, so couldn't find any drive error in the past events.

Probabily have to wait for the new error in order to identify the failing disk.

Thanks

It might be a major problem then a single drive failure. Please call HP support for assistance.
Run ADU & Online Insight Diagnostics to verify drive health.

Hi Billy,

To show events older than those listed in the GUI telnet to the MSA and use the 'show events' command.

Hope this helps,

John
