Re: How to view the EMC LUN in HPUX box
1) EMC should do, if you don know EMC stuff.
2) after assigning LUNs
#insf -eC disk
#ioscan -fnC disk [EMC disk would be should in description field as Symmetrix]
##cd /dev/dsk
#ls -lrt
the last create device files would be the one which just added to server.
You can use them for LVM.

1.How to view the EMC LUN in HPUX box
AS said, you have to use:
# insf -eC disk
# ioscan -fnC disk
Description filed (last one) will tell you.
2.How to add the disk
From storage side-> you have to contact storage team to get it added from storage to houx server
From server to VG -> #vgextend vg_name disk_name

Re: How to view the EMC LUN in HPUX box
Do you have "Powerpath" Installed in your HPUX Box -> Yes means you use
"powermt device=all" -> EMC - Clarion
or "syminq" -> EMC - SySmetrics
depends on which "EMC Storage" you use.
Its also better you check with your storage admin to give you "LUN" newly assigned to this HPUX Box
Once LUNS assigned
#ioscan -fn
# insf -e
# ioscan -fnC disk
Than do double confirm you looks for newly device files create under
cd /dev/rdsk
ls -lrt -> will show the newly created device files with current timestamps
2.>>>How to add the disk<<<
It again depends or you going to "vgextend or vgcreate"
vgextend -> to extend "volume group" once you add the disk
man vgextend -> more information
vgcreate -> create new volume group
man vgcreate -> more information

U can check LUN by
#powermt device=all (EMC clarion) (for LUN)
#ioscan -funC disk
for adding check vgextend man page

Power path is a mutil pathing solution from emc which support Symetrix,clariion,celera,Hitachi,IBM storage arrays, means we can use it for almost all storage systems,
Also syminq or inq should work on all emc storage systems

Re: How to view the EMC LUN in HPUX box
I agree with Johnson, just one more thing.
Sometime you need to made a symcfg discover to get the symmetrix info if you have a symmetrix/dmx array.
Obviously, if you have a clariion, you have to play with navisphere.

Re: How to view the EMC LUN in HPUX box
Without that info no idea which disk is the one you can have!!
Once you know the disk number and they assure you it's masked then on your server run:
symcfg discover
insf -e
ioscan -fnC disk > ioscan.disk
Then you could run:
symdev list | more
Look for the EMC disk number and you should also see it shows the /dev/dsk/c-t-d- entry as well.
-OR-
You can just run:
syminq | grep -i
