Do not override an autocommit under normal circumstances; use the default. See
single-CP mode" on page 239 for details about overriding the autocommit option.
As an alternative, before starting a firmware download, you can connect the switch with a serial console
cable to a computer that is running a session capture. The information collected might be useful for
troubleshooting.

Summary of the upgrade process

The following summary describes the default behavior of the firmwareDownload command (without
options) on the 4/8 SAN Switch, 4/16 SAN Switch, SAN Switch 2/8V, SAN Switch 2/16V, SAN
Switch 2/32, Brocade 4Gb SAN Switch for HP p-Class BladeSystem, and SAN Switch 4/32:
1. Issue the firmwareDownload command.
2. Fabric OS downloads firmware to the secondary partition.
3. The system performs an HA reboot (haReboot). After the haReboot, the former secondary partition
is the primary partition.
4. The system replicates the firmware from the primary to the secondary partition.
You can issue the firmwareDownloadStatus command to view the firmware process.

Switch 2/32, Brocade 4Gb SAN Switch for HP p-Class BladeSystem, and SAN Switch 4/32
The upgrade process first downloads and then commits the firmware to the switch. While the upgrade is
proceeding, you can start another telnet session on the switch and observe the upgrade progress.
NOTE: After you start the process, do not enter any disruptive commands (such as reboot) that interrupt
the process. The entire firmware download and commit process takes approximately 17 minutes. If there
is a problem, wait for the timeout (30 minutes for network problems; 10 minutes for incorrect IP address).
Disrupting the process can render the switch inoperable and require you to seek help from Customer
Support.
Do not disconnect the switch from power during the process; the switch could become inoperable upon
reboot.
