That is correct.  From the perspective of PowerPath, we are managing the device as a whole no matter how it is carved up.
I am usingPowerpath 5.2 on Solaris 10. After doing 'powermt config' , the pseudo devices for my new luns appear on 'forma't like this:   52. emcpower0g           /pseudo/emcp[NAME] 53. emcpower 1c           /pseudo/emcp[NAME] 54. emcpower 2a           /pseudo/emcp[NAME]    My question is how does powerpath pick which slice to use like 0g, 1c or 2a as above?  I normally put all my clariion luns on slice 7 as below.  partition> pCurrent partition table (original):Total disk cylinders available: 32766 + 2 (reserved cylinders)  Part      Tag    Flag     Cylinders         Size            Blocks  0 unassigned    wm       0                0         (0/0/0)          0  1 unassigned    wu       0                0         (0/0/0)          0  2     backup    wu       0 - 32765      255.98MB    (32766/0/0) 524256  3 unassigned    wm       0                0         (0/0/0)          0  4 unassigned    wm       0                0         (0/0/0)          0  5 unassigned    wm       0                0         (0/0/0)          0  6 unassigned    wm       0                0         (0/0/0)          0  7 unassigned    wm       0 - 32764      255.98MB    (32765/0/0) 524240  partition>   BUT on powermt display, they all show as 'a':  Pseudo name=emcpower0aCLARiiON ID=APM00043600813 [DB01]Logical device ID=600601609BB81000D526026545EEDE11 [LUN 77]state=alive; policy=BasicFailover; priority=0; queued-IOs=0Owner: default=SP A, current=SP A       Array failover mode: 1  Pseudo name=emcpower1aCLARiiON ID=APM00043600813 [DB01]Logical device ID=600601609BB81000D426026545EEDE11 [LUN 76]state=alive; policy=BasicFailover; priority=0; queued-IOs=0Owner: default=SP A, current=SP A       Array failover mode: 1  Pseudo name=emcpower2aCLARiiON ID=APM00043600813 [DB01]Logical device ID=600601609BB81000D326026545EEDE11 [LUN 73]state=alive; policy=BasicFailover; priority=0; queued-IOs=0Owner: default=SP A, current=SP A       Array failover mode: 1   is what we see on 'format' just a reference to the disk?  because not all the luns are the same, some are a , c , g...etc. These LUNS will be used for oracle ASM. In the past, I have used this and all showed up as 'a' on 'format' and 'powermt display'. This is the first time I see all of them different on the format output.  Thank you in advance.
