This article describes the procedure to replace the hard disk drive on a CPM-9600 or CPM-8600 in a cp-redundancy configuration.This article describes the procedure to replace the hard disk drive on a CPM-9600 or CPM-8600 in a cp-redundancy configuration.

Cause

To replace the hard disks drive on a CPM-9600 or CPM-8600 in a cp-redundancy configuration.

Resolution

To replace the hard disks drive on a CPM-9600 or CPM-8600

Important: Make sure that the replacement disk has the same version of XOS installed as the current active primary CPM and that the disk partitioning scheme matches that of the current primary CPM in the cp-redundancy configuration.

Note: In the following procedure:
CP1 is the Primary CPM
CP2 is the Secondary CPM

1.   Confirm that the CPMs are 100% synchronized before proceeding by executing the following command.

CBS# show cp-redundancy
 

2.   Open a console connection to CP2. From the Unix prompt, issue the halt command. 

3.   When CP2 has halted, remove the secondary CPM from the chassis.

4.   Remove both
the hard disks from the secondary CPM (as shown in Figure 1 ). It is attached by screws; keep these. Label the disk you removed appropriately (for example: duplicate of "CP_chassis_name_SATA").

5.   Attach the replacement disks to the secondary CPM using the screws. Make sure the screw holes are exactly aligned to the CPM hard drive holes. 

Note: This procedure assumes that the replacement disk has the same version of XOS installed as that on the current Primary CPM.

6.   Re-seat the secondary CPM

7.   Open a console connection to CP2 and observe the boot process.

8.   Log in using admin/admin. 

9.   The CPM will boot into an "Interview" process. Exit the Interview process by typing Ctrl-c. 

10.   When the CBS# prompt appears, enter the following command:

CBS# reset-cp-serial
 

11.   Configure the CPM to be eligible for cp-redundancy.
CBS# configure cp-redundancy 
CBS(config-cp-redundancy)# set this_cp election

12.   Save the configuration.
CBS# wr
13.   Confirm that cp-redundancy is administratively enabled.
CBS# show cp-redundancy
14.   Reboot/reload CP2 using the following command:
CBS# reload module X
Where X = the slot number of the CP2/Secondary CPM 
 

Note: The system will prompt you that you are only allowed to reload the offline CPM.

15.   Observe the boot process. You should see the cp-redundancy process begin. 

16.   Log in to the primary CPM and issue the CLI command show cp-redundancy to verify that the cp-redundancy process continues until it reaches 100%.
