After adding multipath, you cannot see the multipath names when listing the /dev/mapper directory.

Do the following:

Enter:

# vi /etc/multipath.conf

Change the find_multipaths value to no.

Enter:

# wq

# service multipathd reload

You should now see the multipath names.

You receive the following error while mounting the storage:

[root@prime-central-linux4 ~]# mount /dev/mapper/mpathbp2 /images/

mount: wrong fs type, bad option, bad superblock on /dev/mapper/mpathbp2,

       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try

       dmesg | tail or so

Enter:

 <storage-path>

The fmctl status command shows that Fault Management started in KVM, but hangs in “starting” status in the cluster.

Check the SSH password-less connection between the two nodes and KVM.

You must upgrade the server with Red Hat Enterprise Linux 5.5 to 5.8 before upgrading Prime Central.

To upgrade from Prime Central 1.1 to 1.2 in a local redundancy HA configuration:

Shut down the cluster.

Insert the Cisco Prime Central 1.2 USB, navigate to the High Availability/Prime Central folder, and locate the 
primecentral_v1.2_ha_vm.tar.gz file.

Use SSH to connect to the first node.

Copy the primecentral_v1.2_ha_vm.tar.gz file to the first node.

Back up the following directories on both nodes:

/root/ha-stuff/pc

/usr/local/bin

Distribute the file:

# tar -zxf primecentral_v1.2_ha_vm.tar.gz -C / --owner root --no-same-owner

# chmod 755 /root/ha-stuff/pc/*

# chmod 755 /usr/local/bin/*

On the first node only, do the following:

Mount the shared partitions:

# mount /dev/mapper/mpath2p1 /opt/pc

Add a virtual IP cluster service address for the Prime Central service:

# ip addr add 192.168.1.130 dev eth0
