Hi Bakunin,
Like you said, we can increase LUNs in size at storage by adding 1 or more disks to the LUN.
Quote:
Most storage systems offer the possibility to increase LUNs in size. If your system does you can use chvg -g to make the VG aware of such an increased LUN instead of adding new LUNs to the VG to accomodate increased storage demands over time
I have 1 concern here, currently, the max PP of PV is limited at 2032 PPs x 128 MB = 260 GB. Because of this limitation, I cannot add the 1 TB PV whose PPs are greater than 2032 PPs.
If we grow the LUN in size example 500GB in total, it will breach the limits of 2032 PPs. Still acceptable from VG side?
Yes. Exactly.

Really? To quote yourself:
I copy here again. Note that below info is taken from another machine which has big VG and scalable VG.
Big VG it has 2 parameters: Max PPs per VG and Max PPs per PV
Code:
[root@abc] / > lsvg vg_abc
VOLUME GROUP: vg_abc VG IDENTIFIER: 00c1cc1400004c0000000128174b7c57
VG STATE: active PP SIZE: 64 megabyte(s)
VG PERMISSION: read/write TOTAL PPs: 19188 (1228032 megabytes)
MAX LVs: 512 FREE PPs: 3826 (244864 megabytes)
LVs: 10 USED PPs: 15362 (983168 megabytes)
OPEN LVs: 7 QUORUM: 7 (Enabled)
TOTAL PVs: 12 VG DESCRIPTORS: 12
STALE PVs: 0 STALE PPs: 0
ACTIVE PVs: 12 AUTO ON: yes
MAX PPs per VG: 130048
MAX PPs per PV: 2032 MAX PVs: 64
LTG size (Dynamic): 256 kilobyte(s) AUTO SYNC: no
HOT SPARE: no BB POLICY: relocatable
PV RESTRICTION: none INFINITE RETRY: no
DISK BLOCK SIZE: 512 CRITICAL VG: no
But with the scalable VG, we have only Max PPs per VG, the Max PPs per PG disappeared. PP size still remains unchanged like you said (never able to change without recreate)
This disappearance of Max PPs per PG, according to my thinking, remove the limit of max PPs per PV, it means that we can add any PV regardless of its size/PPs while PP size unchanged.
Code:
[root@abc] / > lsvg vg_pa3
VOLUME GROUP: vg_pa3 VG IDENTIFIER: 00fa6d1200004c0000000169ec4b083d

Hi!
How to extend /usr partition in rootvg on AIX 4.3.3-09?
I guess first I'll have to decrease the size of other partition(s) in rootvg?
Thank you! (2 Replies)
on the disk array (EMC Clariion cx300):
we added 3 disk and extended the LUN corresponding to HP-9000 (rp7410)
on HP-UX 11.11:
diskinfo /dev/rdsk/c10t0d0, show more disk space, but
vgdisplay vg13 does not show more space
So the problem is the disk had increased, but vgdisplay does not... (6 Replies)
I am running solaris 10 with Veritas. I want to extend a filesystem. It's an oracle partition (/ora12). How can I find out if there is space available to expand the filesystem and then how does one extend it.
I'm from the HPUX world and so LVM was always how I did things.
Thanks

Hi all,
I need to extend a lv, but unfortunately I do not have enough space on my mirrored Volume group.
I've planned to add 2 more disks to this vg (for mirroring)
But ... what's the next steps to extend my lv using these 2 disks with a valid mirroring ?

Hello,
I have redhat and centos systems that I've only been able to grow the VG by adding more disks. I've been searching the web for a way to extend a volume group by growing the physical disk only and not having to add a second disk. Is it possible?
I can do this with AIX, by just... (0 Replies)
