LUN Expantion, HP-UX, VXVM

[shashi kanth]

I have assigned a 15GB LUN from EVA8K to one HP-UX 11.23 IA box, I have created a VxVM disgroup from that LUN, created several volumes in that diskgroup.

Due to some space issues, I have increased the size of the LUN from 15GB to 25GB on CV EVA, on the HP-UX side, i have executed "ioscan" and "vxdisk scandisks" . But no luck, still VxVM is seeing that disk as 15GB size only.


I rebooted HP-UX, still VxVM sees that disk with 15GB size only.


Anyone throw some light on this ?

hi,

Check weather you assign the new lun on the same port,

also run,

ioscan -fn disk
insf | wc -l [ with this command you will be able to check weather new assign lun are detection on your system ]

Thanks,
Avinash

I did not assigned 2nd LUN to that box.

I assigned only one LUN to that box.

I increased the size of that LUN on CV EVA.

That increased size is not reflected on the HP-UX->VXVM.

hi,

This feature is called Dynamic LUN Expansion - DLE.

first check if you have the following patch
PHCO_35524 for HP-UX 11i v2

#swlist -l product | grep PHCO_35524

if not, installed and you have to run vgmodify command.
read the manual in this link will be more than enough for you.

DLE is a LVM feature!

VxVM != LVM

See if this helps you:
