powerpath question
I attached a solaris 10 box to a cx-500. The server has 1 emulex HBA. I installed Powerpath SE on it. I see both paths on the cx-500 side under the connectivity status.I also see the solaris native devices when I do 'format'. However I dont see the pseudo devices when I do
server_1> powercf -q
NO valid mapping entries in conf file!
I ran powermt config, powermt save, but it still does not create the pseudo devices;
server_1> powermt display dev=all
Device(s) not found.
Does the unlicensed version of powerpath create the /dev/rdsk/emcpower* devices? If it does, what am I missing?
Thanks

Also, ensure persistent binding is enabled to the Emulex configuration file. Run /usr/sbin/lpfc/lputil -> select option 5 - persistent bindings -> select 5 for bind automapped targets -> select 0 for the first adapter (you have only one HBA - or else do the same for all adapters) -> select Y (yes) to bind all automapped targets -> select 2 - bind by port name. -> perform a recursive reboot.
Please note - you need to run this lputil to enable persistent binding before you edit the sd.conf file.
Hope this helps.

devfsadm -C
powercf -q
powermt config
powermt display dev=all
if you will see lun, save a config
poermt save
p.s. check admin guide for powerpath in solaris environment

I have done all that but unfortunately nothing.
$ devfsadm -C
$ powercf -q
NO valid mapping entries in conf file!
$ powermt config
$ powermt display dev=all
Device(s) not found.
I have done this on servers with dual HBAs and licensed powerpath with no issues. This is the first time I am doing on a single HBA box and still no luck.

Is there anything I need to watch before I do this? will it affect anything else? I havent mounted the LUNS on the server side yet.

Since the LUNs are not yet mounted on the server and there is no data, I assume there is no risk in changing the failover mode. However, I'll prefer to take a recursive reboot of the server after changing the failover mode.
My 2 cents what about others?
Thanks,

On clariion:
- changed the HBA failover mode to 1
On the host:
cfgadm -c configure c# (To get the c#, cfgadm -al )
devfsadm -C
powercf -q
powermt config
Thanks for your input guys!
