EVA 4000 random Drive/Mirror Port Errors
On one of my EVA4000 boxes i suddenly recieve random event 060b4709's scattered over various enclosures disks. The warning shows up on a daily bases. Anyone have any idea what they mean exactly.
--- The actual event:
everity: Warning -- not failed but attention recommended or required. A non-data exchange sent to a physical disk drive has timed out.

Re: EVA 4000 random Drive/Mirror Port Errors
THE MIRROR PORT
if it is random daily on the various enclosures/disks, then it could be the problem of the mirror port itself.
The failing element could be either the controller├В┬┤s
a) chip
b) mirror port SFP
c) cable (copper)
EVA4000 has 4 mirror ports
There are the followin LED indications of the mirror port health:
GREEN - normal operation
AMBER - no signal detected or the controller port failure
OFF - no GBIC/SFP detected
NOTE
The firmware cannot determine the root cause of the failure. It can determine only that it was unable to properly communicate with the other mirror port. The problem may be in the transmission or the receiving function of either controller. The controller firmware retries the failed mirror port once per second. The port LED of a failed mirror port will return to green very quickly after the action that resolved the failure.
THE PHYSICAL DISK
if it is always the same enclosure/bay/disk, then it could be the problem of the physical disk
The actual event comes from the
1. DISK BACK END PORT DP-1A
cerp_id - HSV200 controller enclosure rear panel Fibre Channel port attached to the physical disk drive or mirror port: DP-1A
exch_type - Frame exchange type: 2 [0x02]

Re: EVA 4000 random Drive/Mirror Port Errors
We have been experiencing the same entries in our EVA event logs for some time. After having HP Support investigate the issue it was determined that it is a known bug with specific types of fibre drive firmware which will be installed in your EVA. HP confirmed to us however that these errors are benign and do not pose a risk to our data. We had more of a problem trying to get that officially confirmed in writing however ;-)
For your own peace of mind, I would recommend you collect all the EVA controller event logs and open a new case with HP for them to investigate. Until they get back to you with more information I wouldn't worry too much about these entries.

Re: EVA 4000 random Drive/Mirror Port Errors
This problem started since we upgraded our EVA, and filled all the bays with disk drives. The failed disks are random but only within the bay3.
I also see the events EIP17, EIP05 and EIP13.
I think that we must replace the encloser. I don't think that there is other solution.
I dont think that this is a firmware bug. It happens with old and the new disk drives.

Re: EVA 4000 random Drive/Mirror Port Errors
You need to contact HP and get someone with experience to analyze the logs, to see which disks show "missing data" or "dropped frames" and if they are all on the same loop.
