armcopy using va7410

[John Jimenez]

currently we have a script that utilizes "Business Copy" and copies our 40 gig production LUN 122 to the 202 nightly. But here is my problem. LUN 122 (only has one logical volume /vg02/lvol2) is 88% full. The VA7410 will not let me expand this LUN so there is no way to increase it. Any Ideas? Is there a way to armcopy this LUN to a bigger disk? I have never done an armcopy copy manually before. This is a production LUN and it cannot be down very long. FYI we are on HP UX 11i and we have on-line JFS.

In the past, with test environments I removed the LUN and then recreated the LUN and restored the data from tape. But like I said I do not have the luxary of being off line for 2 hours if I can help it.

armcopy is used to manage BC volumes but a BC volume is always a copy with the very same virtual size. You cannot increase sizes!

But what about LVM. Using LVM you can add another LUN to the volume group and grow that way!

So right now I have a LUN122(/vg02/lvol2) 40 gig mounted on /diamond
I just make another LUN124, let say 15 gig). But then will this also need to be /vg02/lvol2? And if so, can you give me the command syntax to do so?

try this,

#armcfg -L numbernewlun -a sizeofnewLun -g redundancygroup IDVA

if you have any doubt I am to your disposition

armcopy only copy the parent Lun

Well, to add a second volume (LUN) to your existing VG you can do the following:

1. create physical volume for use in LVM volume group
>> pvcreate -f /dev/rdsk/cxtxdx (new LUN)

2. extend an LVM volume group by adding physical volumes
>> vgextend /dev/vg02 /dev/dsk/cxtxdx

3. increase space for LVM logical volume
lvextend -L (Total size Mb) /dev/vgxx/lvolyy

4. extend a file system size
extendfs -F (vxfs/hfs) /dev/vgxx/rlvolyy

You will find the command syntax on your respective man pages:

PS: What about assigning points .....

[Emilio Brusa]

Where are the points ??

How Do I Assign Points?
Only the question author can assign points to a given response. If you submit a question or new topic and another member replies to it, you will see a dropdown menu of points next to the reply (you must be logged in to see the menu). Select the point value and then click the "submit points" button. Note that you can rate multiple replies and submit them at one time.
