Single-Blade system

For a single-Blade system, prepare the Blade for removal by doing the following:

1. [ ]

Unmount the file systems and prepare the Blade to be halted by typing:

/nas/bin/server_cpu server_2 -q now

2. [ ] Stop the NAS service on the primary CS by entering:

CAUTION:

Stopping the NAS service disrupts service on the system. Any process initiated

by the Control Station or any commands run from the

/nas

directory are inhibited. Do not to

attempt to run this command while working in the

/nas

directory.

/sbin/service nas stop

This command takes up to five minutes to complete. If this command fails, reboot the CS and try
again.

3. [ ] Halt the Blade by typing:

CAUTION:

When you shut down the Blade, you will lose access to the public networks and file

systems. Verify that the customer is prepared for this action.

/nasmcd/sbin/t2reset pwroff -s 2

4. [ ] Wait three minutes for the previous command to complete and then verify that the Blade has

powered off:

Note:

The

getreason

command can be augmented to provide continuous monitoring of the system

reason codes by adding the watch command. Use

Ctrl/C

to stop end the monitoring. For example # watch

/nasmcd/sbin/getreason

Example Output:

# /nasmcd/sbin/getreason

6 - slot_0 primary control station
- slot_2 powered off

5. [ ] Remove the enclosure from the NAS database:

/nasmcd/sbin/setup_enclosure -removeEnclosure 0

6. [ ] The BE is removed from the NAS database and the NAS service is stopped.

Disconnect the faulted Blade enclosure's two power cables from the rack.

Multi-Blade system

For a multi-Blade system, prepare the Blade enclosure for removal by doing the following:

1. [ ]

Determine the failover status of the Blades by entering:

/nas/bin/nas_server -info –all

Sample Output:

id = 1
name = server_2.faulted.server_3
acl = 0
type = standby
