Hello all,
Hopefully this is in the right section! :) Last monday we had a serious issue on our main production server. We're running Windows Server 2008 R2 (virtualised through Hyper-V 2008 R2), with iSCSI connections to our PS6000 and PS6100 Dell EqualLogic storage. For some reason that night the server lost connection to an iSCSI disk that contains all the .exe files for SAP causing the program to crash. I'm currently out of ideas and was hoping to get some input from others here =D.
Windows Server 2008R2 SP1 with the latest Windows updates installed.
iSCSI initiator driver version 6.1.7601.18386
EqualLogic firmware: V7.0.9 (R400081)
EqualLogic HIT tools on the server: 4.7.1
CommVault backup was running at that time (always scheduled for the time frame)
ID 29 1:53:26: Target rejected an iSCSI PDU sent by the initiator. Dump data contains the rejected PDU.

What caused our SAP process to stop working:

Any help to put me into the right direction would be greatly appreciated!
Kind regards,
