Hi all,

This is odd :) ...

OK so we have a Gen8 recon storage box - running Version 8 - subscription product all good.
The storage is a single large LUN 70TB + .. When I configured it originally on test I used ZFS Single Disk on this LUN - Hardware raid can take care of any problems?

On the Gen9 its replacement I did the same on this time using the same VirtIO SCSI Single HDD Adapter the drive doesn't appear in Windows Setup.
Swap to IDE or VMwareSCSI it appears.
I've tried zeroing the disk and using an LVM - Same Problem.

I've two questions - why isn't the disk appearing on the Gen9

And is it OK to back ZFS single disk with hardware raid - or should I use LVM ?
 
If you want to use zfs you should delete your lun first and switch to hba mode of your controller, eg with somethink like:
ssacli ctrl all show config detail # search for which ctrl and array
ssacli ctrl slot=1 array A delete forced # take right ctrl number and disk array here
ssacli ctrl slot=1 modify hbamode=on # take right ctrl number here
rescan-scsi-bus.sh
Now you should see all disks (which were in the 1 lun before) in PVE.
