eva5000 detailed logging

Hi,

We had an episode on a Win2003 server where two EVA5000 virtual disks were 'lost' by the OS for about 17 seconds.

The disks are presented as fibre channel multipath, so if it were a controller issue on the server, I'd think I would see some information in the logs.

I know the time of the failure, but I can't find any logging on the 'command view EVA web application'. The server hosting 'command view eva' has nothing in the OS (windows 2003 R2) logs.

This might be an obvious question for some, so replying with the obvious would help me out.

Re: eva5000 detailed logging

From Command View you should be able to get the controller event log. Press "get log file" compress and attach here.

Thanks for the assistance. See attached.

In case others are seeking the same thing, the basic steps are:
1. log into the command view eva web application.
2. Click on the controller
3. Click on the 'View events'
4. Click on 'controller event log'

From there you can view/export/whatever.

Re: eva5000 detailed logging

Looks like a pretty clean disk failure for me:

Firmware 4004

2010-feb-12 04:01:57 0-06-07 ASC: 0x19 ASCQ: 0x00 (Defect list error);
2010-feb-12 04:02:00 0-06-07 ASC: 0x0c ASCQ: 0x02 (Write error - auto reallocation failed);
2010-feb-12 04:02:04 0-06-07 A physical disk drive has been rendered inoperable.
2010-feb-12 04:03:08 Reconstructing
2010-feb-12 04:50:36 Reconstructing; Status: success;
2010-feb-18 13:15:05 0-06-07 replaced

Pretty fast transition to failed state, no meesages about problems accessing vdisks.

By the way, firmware 4004 is unsupported, please update to 4100.

Re: eva5000 detailed logging

Is there a way to configure tiny virtual disks (40GB max size) such that the single disk failures won't affect the cluster?

I've had plenty of other disk failures on the SAN (on much larger virtual disks) and no similar disruption of service.

Re: eva5000 detailed logging

Sorry, but No. The virtualisation is so fine grained that even a virtual disk of 1 GByte can be distributed across a disk group with 240 disks (maximum of the EVA-5000).
