ESXi with software iSCSI

Has anyone had any luck using the swiSCSI driver on ESXi? Following the instructions from VMWare.com I get to the point where I have the iSCSI HBA showing up but no LUNs/targets are showing up. The iSCSI target is running on Solaris 10 update 5 and works with other initiators fine. The ESXi initiator (from the logs) sees the targets b...

Failover for Windows booted from iSCSI target using ietd

A Windows endpoint booted over iSCSI blue-screens and reboots as soon as the failover target source comes up. Till that point, Windows appears to be "frozen". The blue screen codes are sometimes 0x00000f4 and sometimes 0x000007a. Now, on failover, the secondary maintains the same iqn and the source of the Windows disk is independent of t...

How do I programatically mount a raw iscsi volume in windows, and get it ready to use?

The API for creating a new volume on our SAN is pretty straight forward. What I have not been able to figure out is how to programatically connect the iSCSI initiator to it, initialize the space (in the windows disk manager sense) and finally format it and mount it is a drive letter. I currently use win2k3, however moving to win2k8 is ...

Creating Emulated iSCSI Target in a Lab/Testing Environment using Windows Server 2008 R2

We have a single server running Windows Server 2008 with Hyper-V installed running 5 virtual machines. I have purchased a second DELL R805 Server so that we can create a fail-over cluster to our current R805 that is currently in production. Right now, our R805 connects via iSCSI to a MD3000i iSCSI SAN. Before we try to roll out the se...

iSCSI / MPIO disks sticks together after targets xcopy deployment

We have the following infrastructure: WUDSS 2003 R2 provides iSCSI targets which are consumed by a Server 2008 R2 cluster and forwarded as pass-through disks to Hyper-V guests. We do not use VHDs for Hyper-V and, until recently, we have used no MPIO for iSCSI. For OS deployment, we have chosen the following scenario: We have pre-confi...

xen randomly causes iscsi mounts to drop, crashing all VMs

I inherited a xen server that is setup to have all the VM images hosted on an iSCSI mounted NAS array. We been experiencing a random (about every 2-3 days) issue where xen would crash all the VMs, leaving nothing but the Domain0 running. What appears to be happening is something causes the iSCI mount to hiccup. Running "vgchange -a y"...
