Do not override an autocommit under normal circumstances; use the default. See "Upgrading firmware in 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. Upgrading 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 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. Use this procedure to upgrade firmware for 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. Verify that the FTP service is running on the host server and that you have a user ID on that server. 2. Obtain the firmware file from the HP web site: http://welcome.hp.com/country/us/en/prodserv/storage.html and store the file on the FTP server. Verify that the FTP service is running and unpack the compressed files preserving directory structures. 3. Use the firmwareShow command to check the current firmware version on connected switches. Upgrade their firmware, if necessary, before upgrading this switch. See "Checking connected switches" on page 77. 4. Connect to the switch and log in as admin. 5. Use the firmwareShow command to check the current firmware version of the switch to verify compatibility with the version of firmware you are going to download. NOTE: For the SAN Switch 2/8V and SAN Switch 2/16V: If you are running Fabric OS 4.2.0 firmware, you cannot downgrade to earlier versions. For the SAN Switch 2/32: If you are running Fabric OS 4.0.2 firmware, you cannot downgrade to earlier versions. 80 Maintaining configurations and firmware
