how do I map hdiskxxx to filesystem

[MAK]

Hello,

We are running AIX-5.1-L on IBM p680 and using HDS-99XX storage.

I am running iostat and it give me all devices statrt with hdiskXXX.

Disks: % tm_act Kbps tps Kb_read Kb_wrtn
hdisk146 0.1 38.8 1.3 180806069 14584
hdisk150 0.0 0.0 0.0 2049 0
hdisk11 0.2 47.7 1.7 222564295 60668
hdisk151 0.0 0.0 0.0 2048 0
hdisk145 0.2 45.8 1.6 213709213 37600

How do I map these devices to actual file systems? Could you please
let me know?

DMP ( Dynamic Multipathing ) being used. Also AIX-LVM used for
creating volumes and filesystem. Here is the volume group list and
its physical/logical volumes for one V.G.

Try lslv -l redo1, this will show you the hdisk devices being used for that
LV which has a filesystem mapped to it by the name of mountpoint /u01

Also try reading the logical volume management guide for AIX 5.2 I'm sure
you will learn a lot by reading this. Good luck!

Try lspv -l <hdisk>.

There must be a command to show the mapping between the vpaths and
hdisks. You will have installed a fileset to use this storage array.
Use lslpp -f <fileset> to see what commands are in the fileset.

You can use df -k to see your mounted filesystem, for example
# df -k

Filesystem 512-blocks Free %Used Iused %Iused Mounted on
/dev/hd4 131072 50232 62% 1731 6% /
/dev/hd2 2097152 595960 72% 21388 9% /usr
/dev/hd9var 2097152 2003848 5% 619 1% /var
/dev/hd3 917504 773744 16% 169 1% /tmp
/dev/hd1 131072 111912 15% 603 4% /home
/proc - - - - - /proc
/dev/hd10opt 131072 53192 60% 1442 9% /opt
/dev/lv01 655360 631336 4% 26 1% /hacmplogs
/dev/tpxlv 8388608 979416 89% 22401 17% /tpx

and then using the command lslv -l <LOGICALVOLUME> you'll be able to
see the mapping, for example

# lslv -l tpxlv
tpxlv:/tpx
PV COPIES IN BAND DISTRIBUTION
hdisk0 064:000:000 0% 064:000:000:000:000
hdisk1 064:000:000 0% 064:000:000:000:000

"lsvpcfg" will list your vpath-to-hdisk mappings. Pipe to grep if the
list is long.

Then "lspv -l vpathx" to see what logical volumes have partitions on
that vpath as you would if it were an hdisk.

Good luck,
Chris

Thanks Chris! lsvpcfg command was the one I had been looking for.

What its equivalent in Veritas world? ( I know know this is AIX forum
but just in case you know it already ). Soon we would be migrating
from AIX-LVM to Veritas Volmgr.

Once again , I appreciate your help.

I'm not familiar with Veritas Volmgr. Sorry. When you convert, I'd
be interested in hearing your thoughts on it.
