how to get a correct vxvm disk size

[ZQiang]

I have a disk that is about 70g in size. I tried to configure a vg using vxvm but it shows the disk as being 48g in size. I am using HP-UX 11.23 vxvm 5.0. How do I get the correct disk size?

The 'diskinfo' command should give you what you need:

# diskinfo /dev/rdsk/c#t#d#

(where #=the value from ioscan.)

Hope this helps!

Hi,

Is it a fresh disk? or already been used in another VG? if so then use vgexport and vgimport.
Yes, diskinfo must get you correct size of disk. If fresh disk, have pvcreate done sucessfully? or you can re run using -f option.

following are my operating and return messages
#diskinfo -b /dev/rdsk/c3t0d0
71687369
#vxdisksetup -if c3t0d0
#vxdisk list c3t0d0
......
public: slice=0 offset=32896 len=48985984 disk_offset=0
......

It seems ur getting wrong device information in VxVM

Refresh the disk info:

#mv /etc/vx/disk.info /etc/vx/disk.info.old
#/usr/sbin/vxconfigd -k -m enable
#ioscan -fnC disk

We only use VxVM on a couple of our FSC Solaris boxes.
So I don't know if there are layout differences to HP-UX.
Interestingly, on Solaris the blocks are in fact only 512B which would even shrink your disk to 23GB ;-)
Just out of curiosity,
what is reported as free within the DG?
e.g.
# vxdg -g used_dg free

Hi Billy,

Have a look at this doc.
