Thanks for sharing Michael. I actually never tried this on ESXi as we only had the classic ESX available at that time.

Had a word with VMware Support. This does work with ESXi, I just had the wrong at the end of the command – should be:

echo “scsi-qlalip” > /proc/scsi/qla2xxx/3

‘3′ being the file representing the inoperable HBA. When we CAT the file, it reported that all target ports were offline, so we knew we were running the command against the correct HBA.

Also, ESXi 4.1U1 automatically initiated a full rescan – all of my datastores are back online for vmhba1 and I didn’t have to reboot!

THANKS!!

This command does not seem to work with ESXi 4.1U1. the path is slightly different (/proc/scsi/qla2xxx/) and what I get back is:

# echo “scsi-qlalip” > /proc/scsi/qla2xxx/ vmhba1
-ash: cannot create /proc/scsi/qla2xxx/: Is a directory

Any advise would be creatly appreciated.

Just make sure that RSCN event are enabled on your switch fabric. This way you won't be needing the work-around. See also VMware KB Article 1002301

Any tips on performing your workaround (echo “scsi-qlalip” …) on ESXi?
