Cisco CRS-1 Fabric Chassis Integrated Switch Controller Card Installation Tasks


First Published: June 23, 2010

Product Numbers: Cisco CRS-1 Router: CRS-FCC-SC-22GE=

The Cisco CRS-1 Fabric Chassis Integrated Switch Shelf Controller (SC) Card supports 22 Gigabit Ethernet (GE) ports for control plane connectivity between line card and fabric card chassis in a Cisco CRS-1 multichassis system. The SCGE card controls the shelf management functions for the fabric chassis and its components.

The fabric chassis has two SCGE card slots. At least one SCGE card must be operational for the chassis to function. A second SCGE card can be installed for redundancy, so that the loss or removal of a single shelf controller card does not bring down a chassis.

The SCGE card is available with a 40 GB, 80 GB, or 160 GB SATA hard disk drive. New SCGE cards are shipped with the hard disk drive preformatted and partitioned with two QNX4 partitions, and one FAT32 partition. Support for the QNX4 file system was introduced in Cisco IOS XR Release 3.8.2. If your version of Cisco IOS XR is earlier than Release 3.8.2, you must reformat and partition the hard disk drive on the new SCGE card to have three FAT32 partitions.

This document explains how to verify the formatting on a new SCGE card hard disk, and how to correct the formatting if necessary. For the majority of customers, the new SCGE card hard disk is shipped with the correct formatting and no further action is required. Table 1 describes the changes to this document.

Initial draft of this document.



Note Support for multiple disk partitions was introduced in Cisco IOS XR Release 3.6. To perform the procedure descibed in this document, you must be running Cisco IOS XR Release 3.6 or later.


Prerequisites for Formatting an SCGE Card Hard Disk

The prerequisites for formatting an SCGE card hard disk drive are as follows:

Physical access to the router

Console access to the Integrated Switch Controller Card


Note See the "Installing and Removing Fabric Cards and Card Components" section in Cisco CRS-1 Carrier Routing System Fabric Card Chassis Installation Guide for instructions on how to remove an SCGE card from, or insert an SCGE card into the Cisco CRS-1 Series Router Fabric Chassis.


Verifying the Format of the SCGE Card Hard Disk

Perform the following steps to verify the format of a new SCGE card for a Cisco CRS-1 multichassis system.


Step 1 Enter the show version command in EXEC mode to verify the version of Cisco IOS XR on your CRS-1 multichassis system:


RP/0/RP0/CPU0:dublin-dsc# show version
 
   
 
   
Cisco IOS XR Software, Version 3.8.2[00]
Copyright (c) 2009 by Cisco Systems, Inc.
...

Step 2 Enter the show media location command in ADMIN mode to verify the current state of the disk storage media. The following example shows the output for a hard disk with two QNX4 partitions and one FAT32 partition:


RP/0/RP0/CPU0:dublin-dsc# admin
RP/0/RP0/CPU0:dublin-dsc(admin)# show media location F0/SC0/CPU0 
Mon Jun 21 10:08:40.186 UTC
 
Media Information for F0/SC0/CPU0.
                   Image   Current 
  Mountpoint       FsType  FsType      State       DrvrPid  Mirror  Flags
=============================================================================
  /disk0:          FAT16   FAT16  Mounted          0036894  Enabled 
  /disk0a:         FAT16   (?)    Not Present                       
  /disk1:          FAT16   (?)    Not Present                       
  /disk1a:         FAT16   (?)    Not Present                       
  /harddisk:       QNX4    QNX4   Mounted          0032793          Formatted 
  /harddiska:      QNX4    QNX4   Mounted          0032793          Formatted 
  /harddiskb:      FAT32   FAT32  Mounted          0032793          Formatted

Step 3 If the hard disk has not been formatted, see the "Formatting a New SCGE Card Hard Disk" section.

If the hard disk has been formatted, verify that the partitioning is correct for your version of Cisco IOS XR. Table 2 lists the correct partitioning for each Cisco IOS XR Release. If the hard disk is formatted correctly for your version of Cisco IOS XR then no further action is required.

.

Table 2 Required Hard Disk Partitions for each Cisco IOS XR Release

Release
Hard Disk Partitions

Release 3.6.0 to Release 3.8.1

Three FAT32 partitions.

Release 3.8.2 and later

Two QNX4 partitions and one FAT32 partition.


If your version of Cisco IOS XR is earlier than Release 3.8.2, and the hard disk has been formatted with QNX4 partitions, see the "Reformatting an SCGE Card Hard Disk for Cisco IOS XR Releases 3.6 and 3.8.1" section.



Formatting a New SCGE Card Hard Disk

Perform the following steps to format a new, unformatted SCGE card hard disk for a Cisco CRS-1 multichassis system. Note that this procedure only applies to previously unformatted hard disks and cannot be used to alter the formatting of a hard disk.


Step 1 Enter the show media location command in ADMIN mode to verify that the hard disk has not been formatted. If the hard disk is unformatted you should see output similar to the following example:


RP/0/RP0/CPU0:dublin-dsc# admin
RP/0/RP0/CPU0:dublin-dsc(admin)# show media location F0/SC0/CPU0       
Mon Jun 21 10:11:03.652 UTC

                   Image   Current 
  Mountpoint       FsType  FsType      State       DrvrPid  Mirror  Flags
=============================================================================
  /disk0:          FAT16   FAT16  Mounted          0036894  Enabled 
  /disk0a:         FAT16   (?)    Not Present                       
  /disk1:          FAT16   (?)    Not Present                       
  /disk1a:         FAT16   (?)    Not Present                       
  /harddisk:       QNX4    (?)  Not Present 
  /harddiska:      QNX4    (?)  Not Present 
  /harddiskb:      FAT32   (?)  Not Present 
 
RP/0/RP0/CPU0:dublin-dsc(admin)#

If the hard disk has not been formatted, continue to Step 2. If the hard disk has already been formatted, see Table 2 to confirm if the hard disk is correctly formatted for your version of Cisco IOS XR.


Step 2 Enter the format harddisk: partition location command in ADMIN mode:


RP/0/RP0/CPU0:dublin-dsc# admin
RP/0/RP0/CPU0:dublin-dsc(admin)# format harddisk: partition location F0/SC0/CPU0
Mon Jun 21 10:12:29.500 UTC
 
This operation will destroy all data on "harddisk:" and partition device. Continue?

Reformatting an SCGE Card Hard Disk for Cisco IOS XR Releases 3.6 and 3.8.1

Perform the following steps to reformat a new SCGE card, which has been formatted with QNX4 partitions, for a Cisco CRS-1 multichassis system running Cisco IOS XR Release 3.6 or Cisco IOS XR Release 3.8.1.


Note Some of the commands in the following procedure are K-Shell (KSH) commands. KSH commands do not have the checks and warnings in place that the Cisco IOS XR CLI commands have. Please ensure you enter each command correctly.



Step 1 Enter the run attach command to attach to the SCGE card:


RP/0/RP0/CPU0:dublin-dsc(admin)# run attach F0/SC0/CPU0

Step 2 Enter the following commands at the KSH prompt to delete any existing partitions and create three new partitions:


fdisk /dev/hd0 delete -a
fdisk /dev/hd0 add -t 6 -p 60
fdisk /dev/hd0 add -t 4 -p 20
fdisk /dev/hd0 add -t 11 -p 20

Step 3 Enter the following commands to mount the hard disk drive and format the three partitions:


mount -e /dev/hd0
setprio 10
mkdosfs -F32 /dev/hd0t6
mkdosfs -F32 /dev/hd0t4
mkdosfs -F32 /dev/hd0t11

Step 4 Enter the following command to list the process ID for the hard disk drive:


pidin | grep hd

Step 5 Enter the following command to end the hard disk process:


kill -9 process id

Step 6 Enter the following commands to view the contents of your hard disk partitions:


fdisk /dev/hd0 show
ls /harddisk:
ls /harddiska:
ls /harddiskb:

Step 7 Enter the following command to return to the normal prompt:


exit
