Define filesystems in Unix Cluster running Service Guard

Robert Sorenson — Sun, 09 May 2010 19:00:17 GMT

I am trying to figure out and/or find documentation that will instruct how to define filesystems in a Unix cluster environment. I have two physical nodes and Oracle package, weblogic package and other packages running the application. the filesystems are to "follow" the package on the failover but I'm not sure how define the association of the filesystems to the package so I don't get false alarms on opposite node.

First, if is this an HP-UX cluster? If some there is a specific forum for Serviceguard on HP-UX.

Are you using ECMT (assuming HP-UX) for the Oracle package? If so, and you follow the instructions, then the mounting and unmounting of the file system, as well as the enabling and disabling of the volume group, is handled by the package control scripts. (The same is true for Linux.)

If you are writing your own package control scripts (certainly not recommended for Oracle) then there is too much to explain here. You'd need to ask more specific questions.

I am not sure what exactly you looking for ....

it looks you want to do some filesystem activitis on cluster nodes ....

herewith attaching the procedure which we follow to add new filesystems in cluster packages....

we have hpux servsers & IBM storage luns...

i think this doc might can help you..

i have attached that, but i don't know where it got disappeared????

Steps:-
----------
Scan new disks
Create new vgs & lvs
Export vg to map file
Import vg in all failover nodes
Deactivate vg (vgchange â a n vgname)
Make vg cluster aware (vgchange â c y vgname )
Active vg exclusively (vgchange â a e vgname )
Mount new new lvs manually with mount command
Take copy of /etc/cmcluster/pkg/pkg.cntl file
Edit /etc/cmcluster/pkg/pkg.cntl & add new vg, lv details
Copy pkg control files to all failover nodes

FOr deactivate vg = vgchange -a n vgname
For make cluster aware = vgchange -c y vgname
activate exclusively = vgchange -a e vgname
