Description:
Disk replacement procedure for TMA 8.7.0 and higher versions.

Disk replacement procedure for TMA 8.7.0+ .

From TMA 8.7.0 onward, the disk replacement does not need a system reboot. Some of the commands used for disk replacement have changed. If you are replacing a faulty disk on TMA 8.7.0 or higher, you will have to follow the steps below.

===================

Shutting Down a failed disk:

1). Enter the User EXEC Level prompt.

    tibco> enable
    tibco#

2). Backup and copy the current config to a remote SFTP server.

    tibco# backup
    tibco# copy current-config sftp://[username@]ip-addr/remote-pathname
Where username, ip-addr, and remote-pathname point to the location where the current configuration database file is copied onto the SFTP server.

3). Confirm that the disk drive is in failure by entering the show disk User EXEC command:

   tibco# show disk
   An example display from show disk with a failed disk drive is:
   Internal disks
    Disk 1 administrative state: enabled
    Disk 1 operational state:    failed
    Disk 2 administrative state: enabled
    Disk 2 operational state:    up
        RAID not in redundant state
        Reload required: no

4). Write down which disk drive is in failure: disk 1 or disk 2.

    In the example in step 3, disk 1 is in failure.

5). Enter the configure command at the Privileged EXEC level prompt:

    tibco# configure
    tibco(config)#

6). Enter the hardware command at the Global CONFIG level:

   tibco(config-hardware)#

7). Shut down the failed disk drive by entering the disk shutdown Hardware CONFIG command:

   tibco(config-hardware)# disk 1 shutdown
where 1 specifies that the failed disk drive is disk 1.

8). Confirm that the failed disk drive is shut down by entering the show disk User EXEC command:

   tibco(config-hardware)# show disk

An example display from show disk with a failed disk 1 is:

   Internal disks
    Disk 1 administrative state: shutdown
    Disk 1 operational state:    shutdown
    Disk 2 administrative state: enabled
    Disk 2 operational state:    up
        RAID not in redundant state
        Reload required: no

You have completed this procedure.

Installing a new disk:

Remove the faulty disk by following the steps given in "Removing a Failed Disk Drive" in Chapter 2 in tib_ma_maintenance_troubleshooting.pdf(https://docs.tibco.com/pub/tma/8.7.2/doc/pdf/tib_tma_maintenance_troubleshooting.pdf) document.

Install the new disk by following the steps 1 through 6 in "Installing a New Disk Drive" section in Chapter 2 in tib_ma_maintenance_troubleshooting.pdf(https://docs.tibco.com/pub/tma/8.7.2/doc/pdf/tib_tma_maintenance_troubleshooting.pdf) document

After step 6 is completed, enable the new disk

7). Enable the new disk drive using Hardware CONFIG command:
    tibco# configure
    tibco# hardware
    tibco# no disk 1 shutdown

8). Run "show disk" command the output should be

    Internal disks
    Disk 1 administrative state: enabled
    Disk 1 operational state:    waiting-for-rebuild
    Disk 2 administrative state: enabled
    Disk 2 operational state:    up
        RAID not in redundant state
        Reload required: no

9). Exit from  Hardware CONFIG command

    tibco(config-hardware)# exit
    tibco(config)# exit

10). Enter the Admin privileged command:

    tibco# admin

11). Rebuild the disks.

    tibco(admin)#disk-rebuild
    To shorten the time required for the system disk rebuild, enter the disk-rebuild-speed high

12). Admin EXEC command, then y for yes to continue:

   tibco(admin)# disk-rebuild-speed high
   Changing the disk rebuild time may impact performance of the router.
   This should only be done if the router is not passing traffic.
   Do you want to continue (y/n)? y

13). Confirm that new disk is recovering

    tibco(admin)# show disk
An example display from show disk with a recovering disk drive is:
  Internal disks
    Disk 1 administrative state: enabled
    Disk 1 operational state:    recovering
    Disk 2 administrative state: enabled
    Disk 2 operational state:    up
        RAID not in redundant state
        Reload required: no
After the system disk rebuild and recovery process is complete, you see a CLI banner and Admin EXEC Level prompt on your computer screen similar to:
   #########################################################
   CLEAR: Disk 1 is up
   #######################################################
   tibco(admin)#

You have completed this procedure.
