MS SQL active/active/active cluster crash

Medium Priority

Last Modified: 2013-11-15
I am new to sql clustering and had 2 different nodes crash in the last 2 days. The nodes came back up and I could then move resources back to them but I would like to track down why this happened. I n the event log I see alot of ISCSI :

Target did not respond in time for a SCSI request. The CDB is given in the dump data.

Where can I find some pointers as to what caused the crash... We have replaced the ISCSI cards in these servers, so I dont think that is the cards......


any help is appreciated

This error means that you have issues with the SCSI stuff.
it could be the hardware (disks, controllers, cables ...), software (drivers, firmware ...) or configuration issue.
you should check with your hardware guys about that.

if you replaced the ISCSI cards, and the error persists, you have to look into the other points.

This turned out to be an issue with both the iscsi card drivers and initiator rev being out of date. Also I had to disable multicast on the iscsi network completely ,
