ESX host keep detecting a deleted LUN

[inforhunter]

I deleted a datastore from vSphere client,and then unmasking the LUN supporting the datastore from the array.but the ESX 4.1 U1 host keep detecting this LUN,and  enties keep appearing in the vmkernel log

vmkernel: 1:20:12:28.308 cpu5:4190)WARNING: vmw_psp_rr: psp_rrSelectPathToActivate: Could not select path for device "naa.xxxx".

Although I reboot my host,these enties keep displaying.

I don't why? Maybe my process to delete the datastore is wrong.

And is there a way to make these log disapear.

Hello,

        If you are pretty sure lun is unmapped from Storage and host is still showing the same.I would suggest you to go ahead and mask the path from esx host which will certainly remove the stale enteries.

For eg:

ESXi 5.x

: # esxcli storage core  claimrule add --rule 192 -t location -A vmhba33 -C 0 -T 0 -L 0 -P  MASK_PATH

ESX/ESXi 4.x:

#  esxcli corestorage claimrule add --rule 192 -t location -A vmhba33 -C 0 -T 0 -L  0 -P MASK_PATH
