Powerpath driver configuration is failing
Hi Community,
We are using a Sun SPARC T5440 (with 4 internal disks) conected to a CLARIION external storage (having 12 disks). The power path is failing to conigure the EMC disks on the Sun server, with following error:
- The pwercf -q command shows the following "NO valid mapping entries in conf file!" :
Device(s) not found.
INFO: powermt config force
Device(s) not found.
INFO: powermt save

So far, we have tried to:
- Upgrade the EMC Navisphere management
- Uninstall and re-install powerpath, using a valid license
- Upgrade to powerpath release 5.2 SP2
- run all of the below commands:
1. devfsadm -C
2. powercf -q
3. powermt config
4. powermt save
5. powermt display dev=all
and still no devices found.
Your help is really appreciated.
BR,
Joyce

Hi Joyce,
drive type unknow status indicating that your 4 disks are failed, hence needs to be replaced.
1. c2t0d0
2. c3t0d0
3. c4t0d0
4. c5t0d0
And, when disks got replaced online O/S configured all those 4 devices automatically (Depends upon H/A & O/S version), run the command devfsadm if O/S doesnt find the devices ( above 4 devices ) to detect , configure and then create the logical device entry. It uses 2 files /devices & /dev.
No need to run the powerpath commands because entry of all above 4 devices are already there and updated in emcp.conf file. If you want to remove all those devices from the system completely ..then you have to run those powermt commands u had mentioned.
Let me know once your problem resolved.
Thanks
