Operating Systems AIX cannot understand my disk layout Post 302582128 by vjm on Thursday 15th of December 2011 03:29:28 AM

Hi,

If you have installed sdd drivers instead of sddpcm then you will find the paths are also mentioned as hdisk. You can check which sdd drivers you have installed by
Code:
 lslpp -l | grep -i sdd

if the output is

"devices.sddpcm.53.rte" then all the hdisks are LUN's mapped to your server.

If the output is

"devices.sdd.53.rte" then the paths are also shown as hdisk. (Mine is AIX 5.3)

You can use "lsattr -El hdiskpower6" and look for the "active_hdisk" it will show all the paths connected to that disk. you can get an idea from the below output

Code:
lsattr -El vpath1

& the output is
Code:
"active_hdisk   hdisk4/6005076801900254B800000000000082/fscsi1"
"active_hdisk   hdisk5/6005076801900254B800000000000082/fscsi0"

Hope this helps you.

Regards,

Hi,

Mine is ds8k storage. I think you have emc storage so check for the drivers it will help to conclude. From your output it seems hdiskpower0 to 21 are the Luns mapped and the hdisk2 to 47 are paths.
Code:
Pseudo name=hdiskpower0
Symmetrix ID=000192601779
Logical device ID=0109
state=alive; policy=SymmOpt; priority=0; queued-IOs=0
==============================================================================
---------------- Host --------------- - Stor - -- I/O Path - -- Stats ---
### HW Path I/O Paths Interf. Mode State Q-IOs Errors
==============================================================================
1 fscsi3 hdisk26 FA 10gB active alive 0 0
0 fscsi0 hdisk3 FA 7gB active alive 0 0

Pseudo name=hdiskpower1
Symmetrix ID=000192601779
Logical device ID=010A
state=alive; policy=SymmOpt; priority=0; queued-IOs=0
==============================================================================
---------------- Host --------------- - Stor - -- I/O Path - -- Stats ---
### HW Path I/O Paths Interf. Mode State Q-IOs Errors

1 fscsi3 hdisk27 FA 10gB active alive 0 0
0 fscsi0 hdisk4 FA 7gB active alive 0 0
