Replacing a secondary node, Replacing all vls9000 nodes with vls9200 nodes – HP 9000 Virtual Library System User Manual

a.
On the primary node, connect to the serial port or use the keyboard and mouse ports to
connect to a console.
b.
Power on the primary node.
After several minutes, a menu will appear on your monitor asking whether the node is a
primary (master, m) or secondary (slave, s) node.
c.
Enter m. The node will then run cable checks and configuration checks.
d.
After the checks are complete the node will reboot automatically. Wait for the primary
node to fully boot.
Rebooting is complete when you receive the “Initializing node#” and then “Initializing
for node# completed.” messages in the systems notifications (if you have DHCP enabled)
of Command View VLS or when you see the login prompt on the terminal.
5.
The warm failover feature will now automatically restore the original configuration and licenses.
Replacing a Secondary Node
CAUTION:
Each VLS node weighs 17.9 kg (39.5 lb) full. At least two people are required to lift
and move each node.
To replace a secondary node:
1.
Remove the existing node from the rack:
a.
Power off the system. See
b.
From the back of the node, make a note of all cable connections then disconnect the
cables.
c.
From the front of the node, loosen the captive thumbscrews until the thumbscrews are free
of the rack.
d.
Pull the node out from the rack until it stops.
e.
Squeeze the release brackets (see
), then pull the node free from the
rails.
2.
Install the new node into the rack. See
Installing the VLS Node into a Rack
3.
Reconnect the cables to the new node exactly as they were connected to the previous node.
4.
Configure the node. See
Configuring the Secondary Nodes
.
5.
Reboot the system. See
.
Replacing All VLS9000 Nodes with VLS9200 Nodes
Prior to the node replacement:
1.
The VLS9000 system must be running firmware version 6.1.0. If your system is not on 6.1.0,
follow the procedure in the HP Virtual Library System Firmware Version 6.1.0 Release Notes
to upgrade.
2.
Schedule sufficient time for the node replacement. The time needed depends on the number
of nodes and the wiring; assume a minimum of 30 minutes per node and an additional two
hours for configuration.
3.
Stop any in-process backups and restores, and disable the VLS in the backup applications to
suspend operations during the node replacement.
4.
Create a firmware version 6.1.0 Quick Restore DVD. Having one DVD for each node will
speed up the Quick Restore process.
To replace the nodes:
1.
Attach rails to all of the replacement VLS9200 nodes; see the instructions in the rail kit.
2.
As a best practice, save the configuration on the live VLS system.
3.
Shut down all VLS nodes. You will start the replacements with the master node.
