PowerPath restore HBA

I have a Windows 2008 Server with 2 HBA's directly connected to an AX150 in SP A0 and SP B0.   I disconnected the SP B0 cable, then intentionally selected 'Remove from config' to see what would happen, figuring that there would be a simple way to add it back.  I could not find one.  I ended up reinstalling PowerPath and rebooting multiple times to get both SP's back online.  

I noticed that there was a powermt restore command, but I couldn't get it to work.  How do you recover an HBA that you remove?

From teh command line:
powermt config
From Device Manager - scan for new devices
From Disk Administrator - scan for new drives
Then powermt config again
then From Device Manager - scan for new devices again and
From Disk Administrator - scan for new drives again
and then the SPB device should be back. Clunky, but it works.

I definitely wouldn't have figured that one out.   I'll give it a try tonight.  Thanks.

For Solaris 8 and 9, all bets are off. Run awaaaaaaay!

But you have Windows, so that's OK.   :-)

I removed the SP B HBA and went to use the powermt command, but there is no config command.  I've tried several different combinations mostly with the powermt check and powermt restore.  

For the powermt restore command, where do I find the hba#?  I just tried hba=all.  I have no idea what this value is supposed to be or where to find it.  This is what it shows:

Usage:
  powermt <command> [class=<symm|clariion|invista|generic|all>]

  powermt check [force] [reconfig] [hba=<hba#>|all] [dev=<device>|all]
  powermt check_registration
  powermt display [ports] [dev=<device>|all] [every=<#seconds>]
  powermt display options
  powermt display paths  [every=<#seconds>]
  powermt load [file=<filename>]
  powermt remove [force] hba=<hba#>|all | dev=<device>|all
  powermt restore [hba=<hba#>|all] [dev=<device>|all]
          [force [hba=<hba#>|all] [dev=<device>|all]]
  powermt save [file=<filename>]
  powermt set mode=active|standby [hba=<hba#>|all] [dev=<device>|all]
  powermt set periodic_autorestore=on|off
  powermt set policy={ad|bf|co|lb|li|nr|re|rr|so} [dev=<device>|all]
  powermt set priority=<priority> [dev=<device>|all]
  powermt update lun_names
  powermt version [format={verbose|legacy}]

Never mind.  It appeared.  Not sure how, but if you happen to know the command that is the equal of powermt config that would be good for future reference.  Thanks.

You have  PowerPath later than version 4.3 - so substitute:
powermt check reconfig
for powermt config
