Storage Multipathing In Solaris10
I 've a doubt about the no. of paths to a disk in my Solaris10 box.

If i run prtdiag i see 12 instances of emulex. Is it 6 dual port HBAs or some other no. how can i check that.

Code:
 prtdiag | grep LPe11002-S
 00    SUNW,emlxs     LPe11002-S
 00    SUNW,emlxs     LPe11002-S
 00    SUNW,emlxs     LPe11002-S
 00    SUNW,emlxs     LPe11002-S
 01    SUNW,emlxs     LPe11002-S
 01    SUNW,emlxs     LPe11002-S
 01    SUNW,emlxs     LPe11002-S
 01    SUNW,emlxs     LPe11002-S
 02    SUNW,emlxs     LPe11002-S
 02    SUNW,emlxs     LPe11002-S
 03    SUNW,emlxs     LPe11002-S
 03    SUNW,emlxs     LPe11002-S

And i 'm running powerpath and no veritas .. how can i check how many paths each disk (SAN) has.

its should be 12 or 6 ?

From the about o/p can you tell me how many paths my LUNs have .. it shows 6 with luxadm display /dev/rdsk/diskname ..


i just want to know that if my system has 6 dual port HBAs y i see only 6 paths y not 12 paths .. i lil confused on this ..

yes, there are 6 dual port cards of which 2 of them are only using 1 port each.
if you want to check if they are using multipathing, you can simply check from the format output and the entry inside /kernel/drv/fp.conf file
