Disk sizes

[Midrange Systems Unix]

How can I find out the internal disk sizes from a command line. I need this info for a script I am writing.

ioscan -C disk
will show something like:
1/2/0/0.3.0 disk HP 36.4GMAN3367MC

This is 36.4 G disk

Hi,

You can use the diskinfo command

# diskinfo -v /dev/rdsk/c?t?d?

Hi,

# ioscan -fnC disk
# diskinfo /dev/rdsk/cXtXdX
and see the size row.

man diskinfo
What you see is what you want!

Best regards,
Ettore

Yet another way:

As long as the disk is part of a VG you can use the pvdisplay command.

# pvdisplay /dev/dsk/c0t6d0
--- Physical volumes ---
PV Name /dev/dsk/c3t6d0
VG Name /dev/vg00
PV Status available
Allocatable yes
VGDA 2
Cur LV 9
PE Size (Mbytes) 16
Total PE 1093
Free PE 133
Allocated PE 960
Stale PE 0
IO Timeout (Seconds) default
Autoswitch On

To find the size take the "PE Size" x "Total PE". In this case 16 x 1093 = 17488 MB

This is the size usable by LVM. The information from diskinfo is the size reported by the disk, which may not all be usable.

As others have said, iocan -fnC disk and diskinfo /dev/rdsk/cXtXdX

Also, if you are SAN attached, then you may have some other tools to look at:

For example, if using EMC, check out the syminq command.
