Brocade FOS Up gradation Steps.
1.
Backing up the existing switch configuration to
the local server by cmd “configupload”.
For Example:
switch1:admin> configupload
Server Name or IP Address [host]: 1.2.3.4
User Name [user]: matty
File Name [config.txt]: switch1_config.txt
Protocol (RSHD or FTP) [rshd]: ftp
Password:
upload complete
Server Name or IP Address [host]: 1.2.3.4
User Name [user]: matty
File Name [config.txt]: switch1_config.txt
Protocol (RSHD or FTP) [rshd]: ftp
Password:
upload complete
For download put configdownload.
2.
Tag all the fiber cable and unplug it from the
switch.
3.
Download the FOS version 6.1.0c from the brocade
site.
4.
Take the putty of the switch.
5.
Enter the version
cmd to check the current version.
6.
Enter the nsShow
cmd to check the entire device directly connected to the switch.
7.
Enter the nsAllShow
cmd to check the entire connected device to the fabric.
8.
Enter the fabricshow
cmd to check all switches in the fabric
9.
Enter the Firmwareshow
cmd to chek the primary and secondary partion.
10.
Enter the
Firmwaredownload cmd to download the new version.
For example:
switch:admin> firmwaredownload
Server Name or IP Address: 10.22.127.127
FTP User Name: JohnDoe
File Name:
/release.plist
FTP Password:
You can run firmwaredownloadstatus to get
the status
of this command.
This command will cause the switch to reset
and will
require that existing telnet, secure telnet
or SSH
sessions be restarted.
Do you want to continue [Y]: y
11.
Enter the firmwaredownloadstatus
cmd to check the current status of the upgrade process.
12.
Enter the firmwareshow
cmd to check the primary and secondary partition version.
13.
Plugin all the fiber cable and check the
connectivity.
14.
Enter the nsShow
cmd to check the entire device directly connected to the switch.
15.
Enter the nsAllShow
cmd to check the entire connected device to the fabric.
16.
Enter the fabricshow
cmd to check all switches in the fabric.
Backing
up Brocade switch configurations
Brocade switches have become one of the most widely
deployed componets in most Storage Area Networks (SANs). One thing that has led
to Brocade’s success is their robust CLI, which allow you to view and modify
almost every aspect of their switch. This includes zoning configurations, SNMP
attributes, domain ids, switch names and network addresses, etc. All of this
configuration information is necessary for the switch to function properly, and
should be periodically backed up to allow speedy recovery when disaster hits.
Each Brocade switch comes with the “configUpload” and
“configDownload” commands to back up a switch configuration to a remote system,
or to restore a configuration from a remote system. ConfigUplaod has two modes
of oepration: interactive mode and automatic mode. To use the interactive mode
to upload a config from a switch named switch1 to an ftp server with the IP
address 1.2.3.4, configUpload can be run to walk you through backing up the
configuration:
switch1:admin> configupload
Server Name or IP Address [host]: 1.2.3.4
User Name [user]: matty
File Name [config.txt]: switch1_config.txt
Protocol (RSHD or FTP) [rshd]: ftp
Password:
upload complete
Server Name or IP Address [host]: 1.2.3.4
User Name [user]: matty
File Name [config.txt]: switch1_config.txt
Protocol (RSHD or FTP) [rshd]: ftp
Password:
upload complete
After the configuration is uploaded, you will have a text
file with you switches configuration on the remove server:
$ ls -l sw*
-rw-r--r-- 1 matty
other 7342 Jul 7 09:15 switch1_config.txt
To restore a configuration, you can use the configDownload
command. Both of these commands allow the paramters to be passed as arguments
to the script, so they are ideal for automation (there is a backup script on
the Brocade support site that can be used to automate configuration backups)
Testing and Restoring the Firmware
version.
1.Enter the firmwaredownload –s cmd and set
the auto commit options to “no”.
For example:
switch:admin>
firmwaredownload -s
Server
Name or IP Address: 10.32.220.100
FTP
User Name: william
File
Name: /pub/v5.1.0/release.plist
FTP
Password:
Do
Auto-Commit after Reboot [Y]: n
Reboot
system after download [N]: y
Firmware
is being downloaded to the switch. This step may take up to 30
minutes.
Checking
system settings for firmwaredownload...
2. Restore
back to the olderversion by “firmwareRestore” cmd.
3.
Then enter the “firmwarecommit” to commit the olderversion.
Checking to be done after the
upgradation activity on switch side.
firmwareShow
Displays the current firmware level on the switch. For SilkWorm directors this
command displays the firmware loaded on
both partitions (primary and
secondary) for both CPs. Brocade reco
mmends that you maintain the same
firmware level on both partitions of each CP within the SilkWorm director.
nsShow
(Optional) Displays all devices directly connected to the switch that have
logged
into the Name Server. Make sure the number of attached devices after the
firmware download is exactly the same
as the number of attached devices prior
to
the firmware download.
nsAllShow
(Optional) Displays all connected devices to a fabric. Make sure the number of
attached devices after the firmware down
load is exactly the same as the number
of attached devices prior to the firmware
download.
fabricShow
(Optional) Displays all switches in a fabric. Make sure the number of switches
in
the fabric after the firmware download is exactly the same as the number of
attached devices prior to the firmware
download.
