cannot understand my disk layout

my users has requested more space to a particular volume group, so i do a lsvg
Code:
honda:/tmp/ab/ecc # lsvg
rootvg
OP24BCKVG
OP24ORAvg
OP24SYSVG
OP24DATVG

the user wants to know what disks are available to be added to any of the vgs listed above, (not including rootvg)

so i do a lspv and i gett the following
Code:
 
honda:/tmp/ab/ecc # lspv
hdisk0          00cae9d54c824462                    rootvg          active

my understanding is the hdiskpowerXX are LUNS made up of the physical hdiskXXs,

so if that is correct, i should be able to create a new volume group called test with hdiskpowerXX that has none and none next to them

also what are the hdisks that have none and none next to them

i clearly understand that all the hdiskpowerXX that have a number and VG name next to it has been assigned to VGs and i know how to get info from them

also let me give you another out from from the following command

take care with your none/none disks, since you are running oracle these may be used by asm as raw disks, ask your oracle admin

I wrote a little script that reads some kind of id from asm disks, to help me find the relation from lpar to vio disks for asm luns easier
try to run it, a none asm disk should not be listed, to make sure run
Code:
oraid hdiskx

, non asm disks should return 00000000

Code:
cat /usr/bin/oraid
#!/usr/bin/ksh
if [ -z "$1" ]
then
lspv | awk '/none/{print $1}' | while read i ; do echo $i $(od -A n -j 12 -N 4 -x /dev/$i | sed 's/ //g') ; done
else                                                                                                                                                                                                                                         
od -A n -j 12 -N 4 -x /dev/$1 | sed -e 2d -e 's/ //g'                                                                                                                                                                                        
fi

but ask your oracle admin anyways, since I don't want to be responsible that you screw up your database Smilie

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.

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
