Chapter 2 Hardware Maintenance : Replacing Disk Drives

Replacing Disk Drives
This section describes how to replace a failed disk drive in a P-7500 system by first shutting it down and removing it, then installing a new disk drive.
Each P-7500 system comes with two disk drives pre-installed in drive bays on the left side of the system. The disk drives are pre-configured as a RAID 1 array.
This section contains the following topics:
Safety Precautions
For your safety, before replacing P-7500 disk drives, review the following safety warning.
Tool and Equipment Requirements
The following tools and equipment are required to remove and install a disk drive in a P-7500 system:
Shutting Down a Failed Disk Drive
To shut down a failed disk drive:
1.
Enter the enable command at the User EXEC Level prompt:
   tibco> enable
   tibco#
The P-7500 CLI is now in Privileged EXEC level.
2.
(Recommended) As a precaution, create a local backup of the configuration database files on the P-7500 system and then store the backup file on an external remote server:
a.
b.
Enter the backup Privileged EXEC command to immediately create a manual local backup of your configuration database file on the P-7500 system:
      tibco# backup
 
Note: CLI show commands may fail if run while the local backup is being created.
(Optional) To confirm your local backup was created successfully, enter the show backup User EXEC command.
c.
Enter the copy Privileged EXEC command to copy the desired configuration database file to the remote server from the P-7500 system:
      tibco# copy current-config
      scp://[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 remote server.
3.
   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.
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)#
The P-7500 CLI is now in Global CONFIG level.
6.
Enter the hardware command at the Global CONFIG level:
   tibco(config-hardware)#
The P-7500 CLI is now in the Hardware CONFIG level.
7.
Enable the new disk drive using the disk no shutdown Hardware CONFIG command:
   tibco(config-hardware)# disk {1|2} no shutdown
   where {1|2} specifies 1 or 2 for the number of the new disk drive.
The CLI responds with this line:
ALERT: This configuration change will not take effect until the
router is restarted. Please restart the router using the
"reload" command.
8.
Enter the reload Privileged EXEC command to restart the system:
tibco(config-hardware)# exit
tibco(config)# exit
tibco# reload
The CLI responds with this line:
This command will cause a reboot of the system
Do you want to continue (y/n)?
You have completed this procedure.
Removing a Failed Disk Drive

Installing a New Disk Drive
To install either a new CHS-HDD250-01-A or CHS-SSD080-01-A disk drive, perform the following procedure:
1.
2.

f.
g.
Close the lid on the disk drive by using your thumbs to slide the lid backward to the front until it clicks back into place (Figure 11).

Figure 13 Installing the Faceplate
c.
Press firmly in on the faceplate until the push pins engage, and the faceplate is flat against the front of the chassis.
8.
Enable the new disk drive using the disk no shutdown Hardware CONFIG command:
   tibco(config-hardware)# disk <1 or 2> no shutdown
where <1 or 2> specifies 1 or 2 for the number of the new disk drive.
9.
   tibco> show disk
An example display from show disk with a waiting-for-rebuild disk is:
   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
10.
Enter the exit command twice:
   tibco(config-hardware)# exit
   tibco(config)# exit
   tibco#
The P-7500 CLI is now in Privileged EXEC level.
11.
Enter the admin command at the Privileged EXEC level prompt:
   tibco# admin
   tibco(admin)#
The P-7500 CLI is now in Admin EXEC level.
12.
   tibco(admin)# disk
   tibco(admin-disk)# rebuild
13.
To shorten the time required for the disk rebuild, enter the rebuild-speed high Disk 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
14.
   tibco(admin-disk)# exit
   tibco(admin)# show disk
An example display from show disk with a recovering disk drive is:
   Internal disks
   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.
