Renamed a windows 2003 host, now show several dead paths

I am connected to both DMX 1000 and Clariion CX 500.

I haven't lost access to the disks. I have 17 disks off the DMX and 1 off theClariion.

Navisphere shows the correct server name under connectivity status and Storage group.

ECC Control Center shows the correct server name.

In PowerPath, for all the DMX devices, it shows 2 failed(dead) and 2 active.

In PowerPath, for the Clariion device, it shows 4 failed, and 4 active.

I need to add another disk from the clariion, but I think I will have the same issue when I add it.

I put in a service request to EMC a few days ago, but I can't get anyone to respond to the ticket...

Powerpath version is 4.4.1.65

Thanks.

i don't think it's going to be an issue presenting new drive. I would just run powermt check and delete all dead paths, then run powermt save. Present new drive, run powermt config and powermt save again.

did you lose access to the disk , or just a few paths showed up dead ? I would not expect host renaming to cause disk access problems, i know DMX does not know anything about names and Clariion may just show the old name in Connectivity status.

I would do as dynamox says, with one addition

run powermt check --> delete all dead paths
run powermt save --> saves current config
(additional) reboot --> this will force drivers and PnP manager to re-enumerate devices

and then continue with adding drives

HTH,
Edwin.

All looks good now. Thanks everyone for your assistance.
