Installing and Configuring MC/ServiceGuard NFS

 

Configuring an MC/ServiceGuard NFS Package

 

See “Example Two - One Adoptive Node for Two Packages with File Lock

 

Migration” on page 64 for a sample configuration using the package

 

control option.

 

 

NOTE

The NFS specific variables have been moved to NFS specific control

 

script in MC/ServiceGuard NFS Toolkit with the A.11.11.02 and

 

A.11.00.05 releases. See section “Editing the NFS Control Script

 

(hanfs.sh)” on page 41 for the details.

 

Editing nfs.cntl for NFS Toolkit A.11.00.04 and A.11.11.01 (or

 

 

lower)

 

For MC/ServiceGuard NFS Toolkit A.11.00.04 or lower for HP-UX 11.0

 

or MC/ServiceGuard NFS Toolkit A.11.11.01 or lower for HP-UX 11i v1

 

using MC/ServiceGuard A.11.09 (or below) framework.

 

Example steps:

1.Create a separate VG[n] variable for each volume group.

VG[0]=/dev/vg01

VG[1]=/dev/vg02

...

2.Create a separate LV[n] and FS[n] variable for each volume group and file system that will be mounted on the server:.

LV[0]=/dev/vg01/lvol1;FS[0]=/ha_root LV[1]=/dev/vg01/lvol2;FS[1]=/users/scaf LV[2]=/dev/vg02/lvol1;FS[2]=/ha_data

3.Create a separate XFS[n] variable for each NFS directory to be exported. Specify the directory name and any export options.

XFS[0]=”/ha_root” XFS[1]=”/users/scaf” XFS[2]=”-o ro /ha_data”

Do not configure these exported directories in the /etc/exports file. When an NFS server boots up, it attempts to export all file systems in its /etc/exports file. If those file systems are not currently present on the NFS server node, the node cannot boot properly. This
