HP 3PAR T-Class Installation and Deinstallation Guide

8. Press CTRL+W to establish a whack> prompt.
a. Type nemoe cmd unset node_rescue_needed and press Enter. The output will
display the message no output.
b. Type boot rescue and press Enter.
c. Monitor the console output process. The node will continue to run POST then it will stop
and display instructions for running node-rescue (see output on the following page). Enter
y to continue.
NOTE: If y is not entered, you will need to redo step 8.
The system installs the OS. This process takes approximately 10 to 15 minutes (rescue
and rebuild of disk = 5 minutes) + (reboot = 5-10 minutes). When complete, the node
restarts and becomes part of the cluster.
This is the procedure for manually rescuing a 3PAR InServ node (i.e.,
rebuilding the software on the node's internal disk). The system will install
the base OS, BIOS, and InForm OS for the node before it joins the cluster.
You must first connect a Category 5 crossover Ethernet cable between the SP's
private/internal network (Eth-1) and the "E0" Ethernet port of the node to be
rescued. Note that the diagram below does not represent the physical port
numbers or configuration of all node types.

This procedure will execute the following Whack commands:
1. net addr 10.255.155.53
2. net netmask 255.255.255.248
3. net server 10.255.155.54
4. boot net install ipaddr=10.255.155.53 nm=255.255.255.248 rp=10.255.155.54::rescueide
This operation will completely erase and reinstall the node's local disk.
Are you sure? (Y/N) No
9. Verify the node status LED is slowly blinking green and provides a login prompt.
10. If applicable, remove the crossover cable from the recently saved node and connect it to the
next node.
NOTE: Reconnect the public network (Ethernet) cable to recently saved node.
11. Repeat steps 7 through 10 for each node.
12. Log on to a node as a console user.
13. Choose option 2, Network Configuration to set the network configuration for the system. Follow
the prompts to complete the network configuration.
NOTE: The cluster must be active and the admin volume must be mounted before changing
the network configuration.
NOTE: Access STATs to obtain the network information or request it from the system
administrator.
14. Press Enter.
15. Before deconfiguring the node rescue, disconnect the crossover cables and reconnect the
public network cable.
16. Return to the SP Main menu and perform the following:
a. Choose 1 ==> Deconfigure Node Rescue.
b. Choose X ==> Return to previous menu to return to the main menu.
c. Choose 7 ==> Interactive CLI for a StoreServ,, then select the desired system.
