Service Guard question

[George_231]

I have a very limited experience with Service Guard to the extend of one or two command. I have the following task:
MAC - GM ONSTAR - Prod server uspls038 needs unmount file systems and delete service guard packages.
Start Time: 10/13/05 21:00 End Time: 10/13/05 23:59 (EST)

SA to unmount the following file systems on uspls038 and delete the service guard packages which contain these file systems.

The osp4 package
/ldata/pln1/67osp4data1
/ldata/pln1/67osp4logs1

The obp4 package
/ldata/pln1/68obp4data1
/ldata/pln1/68obp4logs1

The databases on these mount points are no longer running and have been archived. We are doing this to free up the following LUN's for the storage.
Could someone give me some instructions.
I'll greatly appreciate that.

The package startup scripts, usually in /etc/emcluster will show what volunge groups are mounted by the packages.

You merely use cmhaltpkg to halt the package and the volume group should umount.

You will need to potentially do this on the failover nodes as well.

1)Halt the packges by

cmhaltpkg -n servername pkg_name

2)verufy using cmviewcl -vp pkg_name

3)delete the package using

cmdeleteconf -p pkg_name

4)go to /etc/cmcluster/pkg_name

edit pkg.cntl file and see the LVs and VGs configured .

5)check that all the Vgs specified are deacivated now by vgdisplay -v vg_name .


6)take map file for these VGs for backup and export Vgs .

vgexport -v -p -s -m /tmp/vgname.map -f vgname.disks vgname

vgexport -v vgname .

7)verify that these VGs are removed by

strings /etc/lvmtab |grep vgname

8)vgname.disks file will contain all the c?t?d? s freed from this VG , you can reclaim these disks .

9)finally remove the package directory ,

/etc/cmcluster/pkg_name on primary and alternate nodes.

10)remove if there was ny host file entry in /etc/hosts file.



Have fun ,
