Pdisks
I have added a couple of new drives to my AIX 5.2. I was wondering how to view them and see what space is available for me to use in a hdisk .
Thanks
Dave

What sort of disks are they?
If they are installed correctly, a reboot or running cfgmgr should configure them as hdisks for you.

Actually some of the drives space from them is already in use divided into 4 hd25 and hd28 and hd27 and hd29. I know there is some space left on these to grow one of my other file spaces with. It would help if I could see what pdisk correlates with what hdisk? I think there is a command that lets me see that?
Thanks

SSA, SAN, or was the pdisk a red herring and they are SCSI?

In Aix every physical hard drive is a PV i.e physical volume. I assume that you have attached the hard drive to the system run the cfgmgr command after that if you have the version 5.3 then you can run the smitty lvm , or just type lspv command that are you seeing any hdisk 0 .... etc etc ..... note that if that disk is available to the system or not then after either you can extend the existing LV (Logical Volume like data vg , rootvg ) by extendvg <vgname>

Hope it helps!!! I tried to explain you as much as I can imagine , you can ask again in details.

Cheers!!!

ok now that I got some where I may be able to explain what i need a little better I found out that pdisk23 is hdisk25 and pdisk26 is hd28. What I would like to know now is how much space is left on them for me to use. Does that make sense?
Thanks
Dave

Hi,
Try these
Code:
lsattr -El hdisk25 # will display some params along with the size of the disk
lspv |grep hdisk25 # identify VG of hdisk25
lsvg vg_of_hdisk25 # look for the FREE PPs line, thats what you're looking for
