Hi,
If you already have vg then just using lvcreate command you can create new lv see the example
lvcreate -L sizeinMB -n myvolume vgname
here -L Size of logical volume in megabytes
-n is name of your lv.

#lvcreate -L 1024 -n lvol4 vg03
#newfs -F vxfs -o largefiles /dev/vg03/rlvol4
#mkdir /data
#mount /dev/vg03/lvol4 /data
add entry into /etc/fstab
# vi /etc/fstab
/dev/vg03/lvol4 /data vxfs defaults 0 2

same you can do using shm in 11.31

Hi,
A good white paper about 11.31 and lvm v2
http://docs.hp.com/en/lvm-v2/L2_whitepaper_8.pdf
In this case you use for example the option -V.
Hope it helps

Re: VG creation on HPUX 11.31

The persistent device files reside under /dev/disk/* and /dev/rdisk/* respectively.

The commands you need to run are :

ioscan -funNCdisk
insf -eCdisk
ioscan -funNCdisk

Dear All,

if i do insf ,whether it will create both /dev/rdsk/cxtxdx and /dev/rdisk/diskNN ????

Re: VG creation on HPUX 11.31

If you run the above command insf -eCdisk it should create both the legacy and persistent device files, i.e. :

/dev/dsk/*
/dev/rdsk/*
/dev/disk/*
/dev/rdisk/*

if the new luns have been presented to the system and the system can see them.

hi,

with 11.31 and the new mass storage stack there should be no need to do insf commnands for new or modified luns

these should be picked up automatically and the persistant dev files created

check the luns with ioscan commands

#ioscan -m lun

and such like

see more details here

http://www.docs.hp.com/en/MassStorageStack/The_Next_Generation_Mass_Storage_Stack.pdf

and creation of vg's or lv's is basically the same, just a difference in the dev files but you can use either, legacy or persistent.

#ioscan -m dsf
#ioscan -funNC disk

for example
