Solaris - Powerpath new pseudo names disappear upon reboot

Hi All,

I've got a problem, I've got a solaris 10 box that's causing me some grief.  Historically the box had 20 LUNs which powerpath was quite happy to manage.  Recently we added another 20-25 LUNS and powerpath was quite happy to manage these new LUNS.. However the server hadn't been restarted until now, upon restart the server still see's the original 20 luns however the new 20-25 LUNS would not mount.

Upon investigation we found that the new 20-25 LUNS were still visable by the host ie power display dev=all could see all of the LUNS but the pseudoname had vanished off the 20-25 recently added LUNS. 

We can get the pseudoname by clearing the emcp.conf and powermt.custom and running the powermt config, powermt save commands but upon restart I am back in the same problem where my pseudonames for my new LUNS have vanished.

Can anyone provide any advice as to what I am missing

Cheers

Paul

in the below output LUN 78 (emcpower14a) was still visible/accessible/could be mounted by the host however LUN 101 (pseudoname disappeared after restart) was not mountable.
