Help with BSODs

[hotwired007]

I have a couple of win2k3 servers that BSOD when ever there is any interuption to the iSCSI network ie one switch is powered off (4 Server Proxmox 2.1 cluster, storage based on Dell MD3200i iSCSI with multipath configured and working correctly). there are 6 Win2k3 servers (4 Web servers, 1 DC and 1 running a legacy backup system) and its only two (the same two each time) that ever have an issue if one of the two switches fails or is unplugged. All of the other VMs carryon running fine - a mixture of linux and windows boxes - covering most of the versions of windows and several debian boxes running different services.

Aside from upgrading to the newest Proxmox and upgrading to a newer server OS does anyone have any suggestions? (Both of these are NOT an option atm)

Each VM is using QEMU x64 CPU and standard IDE drivers with no write back - same as ALL other Win2k3 VMs.

A few questions that may help in troubleshooting.

1. Do all of the Windows VMs, including the VMs that don't crash, use iSCSI in the same fashion? e.g. All of the Windows VMs have their virtual OS disk on the iSCSI target.

2. Do both of the VMs that BSOD have the same error code?

3. What is (are) the error code(s) that BSOD presents?

Yup - they're all on the same iSCSI virtual disk.

2. Do both of the VMs that BSOD have the same error code?

yup

3. What is (are) the error code(s) that BSOD presents?

i get a mixture of NTFS errors and this code: 0x805000f
