27.4 Changing NNMi from HP-UX or Solaris to Linux in a High Availability Cluster
You can change NNMi from HP-UX or Solaris in a High Availability Cluster to Linux in a High Availability Cluster. On Linux, you can use either Veritas Cluster Server or HA monitor.
This procedure uses the following four servers:
-
Server A is the current active cluster node running on HP-UX or Solaris.
-
Server a is the current passive cluster node running on HP-UX or Solaris.
-
Server B is a new primary cluster node that will be running on RHEL 6.
-
Server b is a new secondary cluster node that will be running on RHEL 6.
Both Server B and b cannot emply the same hardware configuration as the current Server A, a.
-
On Server A and a, unconfigure NNMi from an HA cluster.
Refer to 17.7 Unconfiguring NNMi from an HA cluster described in NNMi 10-50 Setup Guide.
Make sure to run the following steps described in Setup Guide.# Otherwise DB is NOT transferred.
- #: Setup Guide refers to one of the following manuals.
-
- JP1/Cm2/Network Node Manager i Setup Guide (3021-3-242-20)
- Job Management Partner 1/Consolidated Management 2/Network Node Manager i Setup Guide (3021-3-343-20)
-
On Server A, run backup processing.
Make a full backup of NNMi using the following command on current active cluster node:
nnmbackup.ovpl -type online -scope all -target temporary_location
You must use the online option. For details, see the nnmbackup.ovpl Reference Page.
-
On Server B and b, run step 2 and step 3 described in 27.1 Changing NNMi from HP-UX or Solaris to Linux in NNMi 11-00 Setup Guide.
-
On Server B, run step 4 through step 7 described in 27.1 Changing NNMi from HP-UX or Solaris to Linux in NNMi 11-00 Setup Guide.
-
On Server B and b, run step 8 and step 9 described in 27.1 Changing NNMi from HP-UX or Solaris to Linux in NNMi 11-00 Setup Guide.
-
On Server B, delete the following line in /var/opt/OV/shared/nnm/conf/ov.conf
# HA_EVENTDB_DIR=<mount point of shared disk>/NNM/dataDir/shared/nnm/databases/eventdb
-
Configuring HA between B and b.
Refer to 19.4 Configuring HA described in NNMi 11-00 Setup Guide.
- Important
-
For HA Monitor, you perform the configuration procedure without using nnmhaconfigure.ovpl. For details about the configuration procedure, see the Release Notes.
