Hi,
I'm trying to add a datastore to an ESXi5 host. The host access to the iSCSI storage seems to be ok but when I rescan the storage adapters I get an error I haven't seen before.
Error while rescanning adapter vmhba36. Error was Unable to scan VMkernel SCSI subsystem for new devices.Sysinfo error on operation returned status : Maximum allowed SCSI paths have already been claimed.
I only have 6 devices with 12 paths so I'm not sure what is going on here. Can anyone help?
Thanks,
Steve
So when you list the paths how many are displayed ??
under Hosts and clusters-> host-> configuratiuon-> storage adpators
If you click an adaptor it should show you target /devices/paths in details.
whats is it saying there?
I figured it out. The GUI was lieing to me - i didn't show any dead paths. But when I logged into the host and ran an esxcfg-mpath -l there were over 1000 dead paths. I tried to delete them but that didn't work so I rebooted the host. That sorted things out and I can add the storage ok now.
Thanks for the help.

thanks for updating.
in the future if this occurs you might be able to do that without rebooting
try esxcfg-rescan -d adaptor where adaptor is your adaptor you are targeting, in your case vmhba36
that scans for dead paths.
