Powerpath on solaris 10 with missing pseudo device names.

Hi all,

I got a two node oracle rac cluster, running on solaris 10 with power path Version 5.2 SP 2 (build 12)

Node2 got rebooted and 6 pseudo device names out of total 22 have been lost.

So after reboot, I can still see 16 emcpower... devices, emcpower0a through emcpower15a.

For the 6 in question, emcpower16 to emcpower21, I can see the LUN ID, device ID, path health etc by running "powermt display device=all".

I obtained the pseudo device names that should be set for these 6 LUNs by comparing them against node1's pseudo devices.

I tried several emcpadm commands, including exporting mappings from node1 to import them to node2 but none have worked so far.

Is there a way to assign a pseudo name for a device visible to server?

Thanks in advance.

Here is a snipped from powermt display dev=all. You can see LUN 86 is missing pseudo device name.

Pseudo name=emcpower15a
