Doubt in Package Creation

vjta — Sat, 20 Sep 2008 11:14:53 GMT

Hi all,

I m using 2 nodes Cluster .
Nodes are Running with HP-UX 11.31 with SG Cluster 11.18

In my cluster already 2 Packages are running now i want to add one more package my doubt is
Can package be created by just making PKG directory & simply copying cntl files & PKG config files of existing PKG to this newly created PKG directory & making appropriate changes for the respective Package like VGs LVs & PKG IP.
Or by cmmakepkg is better.

regards
vjta

cmmakepkg does exactly the same - generate package files.

If youcopy package files from another - carefully change the settings to avoid mistakes.

Hi,

yes you can do the way you said. just be sure you changed every line that is needed. then apply the package.

Thanks to both of u.

If i am assigning SAN storage ,then what are the steps involved like
shall i run insf cmd to both nodes or in single node it will do.
Actually i m using the steps like:
Assigning LUNs to Nodes,it will appers in both the nodes.
Create VGs for Package.
Exporting VGs by
vgexport -p -s -v -m /tmp/VGNAME.map /dev/VGNAME

transfer these map files to 2nd NOde thru FTP

In 2nd Node importing VGs by
vgimport -s -m /tmp/VGNAME.map /dev/VGNAME

& after that PKG creation by changing appropriate changes in PKG.cfg & PKG.cntl files.

My doubt is in VG cration steps.

Pls put some light.

Thanks & regards

Hi,

running insf on single node is not enough. how the device files get created on other node?
Once you assigned the LUNS, run ioscan on both nodes to verify these LUNS are visible.
run insf on both nodes to create device files for the new LUNS.
Also make sure that the device files are identical. otherwise you will have to import with respective device files.

Follow these steps:

Create cluster VG in node1(exp: vg02)
# pvcreate â f /dev/rdsk/cxtydz
#mkdir /dev/vg02
#mknod /dev/vg02/group c 64 0x020000 (use unassigned minor number)
#vgcreate /dev/vg02 /dev/dsk/cxtydz
Create the logical volumes as per the customer requirement.
create file systems then mount and check
#lvcreate â n - L /dev/vg02
#newfs â F vxfs /dev/vg02/
#mount
#umount
#vgchange â a n /dev/vg02
#vgexport -p â s â m /tmp/vg02.map /dev/vg02
# rcp /tmp/vg02.map node2:/tmp/vg02.map

Create cluster VG on node2

#mkdir /dev/vg02
#mknod /dev/vg02/group c 64 0x020000
#vgimport â m /tmp/vg02.map
#vgchange â a y /dev/vg02
Mount the logical volumes and check then unmount
#vgchange â a n /dev/vg02

Hope this helps

Hi VJTA,

I suggest you refer to the package creation steps in the serviceguard manual. It has all the info you need.

While creating VG please take care of the minor number. It should be same in both the nodes.....

Cheers

Vita,

Yes, you need to run ioscan and insf on both nodes as both nodes must be aware of same luns comming from storage box.

If you have already configured existing cluster packages then you better go with same process here as time you will be consuming for searching n updating will be more i believe.

Follow the steps for Package creation

#mkdir /etc/cmcluster/PKG
#cmmakepkg â p /etc/cmcluster/PKG/pkg.conf---
This will create package template
edit and save this file

#cmmakepkg â s /etc/cmcluster/PKG/pkgname.cntl
This will create controle file to control the behaviour of start and stop of package
--------- edit and save this file

Copy pkgname.cntl to all other node

#cmcheckconf â v â C /etc/clcluster/ori.config â k â p /etc/cmcluster/PKG/pkgname.conf

#cmapplyconf â k â v â C /etc/clcluster/ori.config â p /etc/cmcluster/ PKG/pkgname.conf

Disable the vgactivation while system boots in /etc/lvmrc . Make it 0

start the cluster on primary node
cmruncl and get the new package running :-)

Vita,

Folks are working hard to try and give you a step-by-step instruction for you do create a package. But is is fairly clear that before you do this you need to start reading the manuals.

Here's where you can read about SG & packages: http://docs.hp.com/en/ha.html
