Fabric OS 6.2 administrator guide 215
High Available sync state
HA synchronization occurs when two CPs in an enterprise-class platform are synchronized. This state
provides redundancy and a non-disruptive firmware download. In order for a firmware download to
successfully occur, the two CPs in an enterprise-class platform must be in sync.
If the CPs have mixed versions when you enter the
firmwareDownload
command, the CPs may not be in
HA sync. In this case, you need to enter the
firmwareDownload –s
command first to upgrade or
downgrade the standby CP to the same level as the active CP first, and then upgrade the CPs to the desired
version of firmware.
NOTE:
Do not run mixed firmware levels on CPs.
Table 56
shows the sync state of an enterprise-class platform that has different Fabric OS versions installed
on the active and standby CP. Use the table to determine if you need to use the
firmwareDownload -s
command.
A nondisruptive firmware download, which is performed by entering the
firmwareDownload
command
without the
–s
operand, is supported only if you are upgrading from Fabric OS 6.1.x to 6.2.0. If you are
downgrading from Fabric OS 6.2.0 to 6.1.x, you must enter the
firmwareDownload -s
command
option as discussed in ”
Test and restore firmware on switches
” on page 227 and ”
Test and restore firmware
on enterprise-class platforms
” on page 228.
NOTE:
Downgrading from Fabric OS 6.2.0 to 6.1.x is disruptive to FC traffic.
Preparing for a firmware download
Before executing a firmware download, HP recommends that you perform the tasks listed in this section. In
the unlikely event of a failure or time-out, the preparation tasks that are described in this section will enable
you to provide your switch support provider the information required to perform advanced troubleshooting.
HP recommends that you perform a
configUpload
to back up the current configuration before you
download firmware to a switch. See ”
Configuration file backup
” on page 165 for details.
1.
Read the release notes for the new firmware to find out if there are any updates related to the firmware
download process.
2.
Connect to the switch and log in as admin. Enter the
firmwareShow
command to verify that the
current version of Fabric OS. HP does not support upgrades from more than one previous release. For
example, upgrading from Fabric OS 6.1.0x to 6.2.0x is supported, but upgrading from Fabric OS
6.0.0x or a previous release directly to 6.2.0x is not.
In other words, upgrading a switch from Fabric OS 6.0.0x to 6.2.0x is a two-step process—first
upgrade to 6.1.0x, and then upgrade to 6.2.0x. If you are running a pre-Fabric OS 6.0.0x you will
need to upgrade to 6.0.0x, and then to 6.1.0x, and finally to 6.2.0x.
