Hi,

I had to reinstall DSS, because we had done some test with CentOs.

I have now reinstalled DSS:

created a vg - w/o any problems (sorry, we had never a problem w/ vg; my mistake, it was always a poblem w/ the next step)

crated a lv, and the problems started
~10 min after creating, the system becomes more and more slow
~30 min after creating, the system doesn't response any longer

I was able to connect w/ ASM
Before creating the lv, ASM could see both controller
we are using two controllers:
Adaptec 2610A with 4 HDD for the DSS System, and planed for images/iso...
Adaptec 6805 with 8 HDD for FC

Now, ASM only see the 2610A controller, but no longer the 6805
I was able to save the logfile (while the system no longer response to anything).

How to att. a logfile (txt) to this board ????

As i can see from the logfile, one HDD timedout:

dss Command timeout: controller 2, channel 0, SCSI device ID 7, LUN 0, cdb [2a 00 20 a1 f4 00 00 02 00 00 00 00]

followed by:
dss Sense data: Illegal request (PARAMETER NOT SUPPORTED). Controller 2, channel 0, SCSI device ID 7, LUN 0, cdb [2a 00 21 4f fe 00 00 02 00 00 00 00], data [70 00 05 00 00 00 00 00 00 00 00 00 26 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00]

An error occurred while accessing the logical device: controller 2, logical device 0
An error occurred while accessing the logical device: controller 2, logical device 252

The HDD are all new, and I had no similar problems while running with CentOs.
I have ordered 2 more HDD's, to see if this solves the problem.

Nevertheless, a dregraded RAID should not bring the whole server down (we have used a RAID 10). A single failed HDD should not be a problem.

As soon I have done some more tests, I will get back to you
