Hello,
I have 2 hosts ESXi01 & 02 running on VMware 5.5.0. There is a tape drive IBM TS2250 connected to ESXi02 and a virtual machine on ESXi01 which needs access to this tape drive. When I try to add it in VM settings it's grey and unavailable, but it's available for VMs on ESXi02 where it's connected.
Funny thing is that it worked before but after power failure, I had to start the VM quickly without any physical access to the server room, so I had to temporarily delete this SCSI device (which was off) to be able to start the VM and I can't add it back now. I'd be grateful for any tips.
