SmartArray P212, errors on RAID-Z (error 0x0015 reported by hpacucli)

[Katan]

HI,

I´m using the onboard controller of a Proliant ML110 G7 and a SmartArray P212 on with ZFS Raid-Z using non HP Drives. It is working fine most of the time but I noticed that some times a disc on the P212 was reported as UNAVAILABLE, upon boot, so I did a firmware update, which apparently fixed the issue, but today I noticed that my array did freeze (IO locked), and on the array status a disc was unavailable and the other reported as faulty (only them on the P212). Upon rebooting the system it was working again so now I´m scrubbing the array to make sure the data is fine.

So, I did a diagnostic with the HPACUCLI on Linux, in which was reported 3 lockups on the P212 controller, does anyone know what is the error 0x0015??
