how to find out disk capacity

UNIX AIX
1

Hi,

I would like to know how to find out disk capacity if it is assigned from the storage as a lun.

as per below command , I am unable to find out disk capacity.

$ bash
bash-3.00$ lspv

hdisk1          0001579a7fa3c086                    None
$ lscfg -vl hdisk1
  hdisk1           U7998.61X.06157AA-V2-C2-T1-L820000000000  Virtual SCSI Disk Drive

you can try df -k (Man df for options) which will give you free space and total spaces

Hi.

You can use:

$ getconf DISK_SIZE /dev/hdisk1

This shows the size in Megabytes.

4

bootinfo -s <hdisk>

5

Or else use

bootinfo -s hdisk1

again size in MB.

Can 'df' tell you how much is used ? on the filesystems

depending on the storage subsystem, the driver may give you an answer too

for sddpcm drivers (IBM storage)

take a look at the driver documentation for your subsystem

df -g .will show you your /hd4 (thats root dir )

lsvg .will show Volume Groups (ie Rootvg)
lsvg -l Rootvg . will show properties of this Volume Group
lsvg -o .will show active VGs

hdisk1          0001579a7fa3c086                    None

"none" means device hdisk1 no belongs to any volumen group->no any volumen -> no any filesystems -> can't use command fs.
