8 Installing and maintaining firmware Firmware download process overview Fabric OS 6.2.0 provides nondisruptive firmware installation. This chapter refers to the following specific types of blades inserted into either the HP StorageWorks 4/256 SAN Director or HP StorageWorks DC SAN Backbone Director and HP StorageWorks DC04 SAN Director Switch platforms: • FC blades or port blades contain only Fibre Channel ports: HP StorageWorks 4/256 SAN Director 16 Port 4Gb Blade, HP StorageWorks 4/256 SAN Director 16 Port 4Gb Blade, HP StorageWorks SAN Director 48 Port 4Gb FC blade, HP StorageWorks SAN Director 6 Port 10Gb FC blade, and HP StorageWorks SAN Director 16 Port 8Gb FC blade, HP StorageWorks SAN Director 32 Port 8Gb FC blade, HP StorageWorks SAN Director 48 Port 8Gb FC blade. • AP blades contain extra processors and specialized ports: B-Series Multi-Protocol Router Blade and HP StorageWorks B-Series iSCSI Director Blade. • CP blades have a control processor (CP) used to control the entire switch; they can be inserted only into slots 5 and 6 on the HP StorageWorks 4/256 SAN Director, slots 6 and 7 on the HP StorageWorks DC SAN Backbone Director, and slots 4 and 5 on the HP StorageWorks DC04 SAN Director Switch. • CORE8 and CR4S-8 core blades provide ICL functionality between two HP StorageWorks DC SAN Backbone Directors: CORE8 blades can be inserted only into slots 5 and 8 on the HP StorageWorks DC SAN Backbone Director. CR4S-8 blades can be inserted only into slots 3 and 6 on the HP StorageWorks DC04 SAN Director Switch. NOTE: For more information on troubleshooting a firmware download, see the Fabric OS Troubleshooting and Diagnostics Guide. You can download Fabric OS to a director, which is a chassis; and to a nonchassis-based system, also referred to as a switch. The difference in the download process is that directors have two CPs and nonchassis-based systems have one CP. Use the firmwareDownload command to download the firmware from either an FTP or SSH server by using either the FTP or SCP protocol to the switch. Or, on the HP StorageWorks 8/8 and 8/24 SAN Switches, HP StorageWorks 8/40 SAN Switch, HP StorageWorks 8/80 SAN Switch and the HP StorageWorks DC SAN Backbone Director and HP StorageWorks DC04 SAN Director you can use an HP StorageWorks B-Series 2G USB Drive (AK864A). The new firmware consists of multiple files in the form of RPM packages listed in a .plist file. The .plist file contains specific firmware information (time stamp, platform code, version, and so forth) and the names of packages of the firmware to be downloaded. These packages are made available periodically to add features or to remedy defects. Contact HP support to obtain information about available firmware versions. All systems maintain two partitions of nonvolatile storage areas, a primary and a secondary, to store two firmware images. The firmware download process always loads the new image into the secondary partition. It then swaps the secondary partition to be the primary and High Availability (HA) reboots (non-disruptive) the system. After the system boots up, the new firmware is activated. The firmware download process then copies the new image from the primary partition to the secondary partition. In dual-CP systems, the firmware download process, by default, sequentially upgrades the firmware image on both CPs using HA failover to prevent disruption to traffic flowing through the enterprise-class platform. This operation depends on HA status on the enterprise-class platform. If the platform does not support HA, you can still upgrade the CPs one at a time, using the firmwareDownload -s command. This command allows you to enable or disable autoreboot, and autocommit modes, on switch and enterprise-class platforms. On enterprise-class platforms, the -s option enables you to upgrade a single CP. See the "Test and restore firmware on enterprise-class platforms" on page 228. Fabric OS 6.2 administrator guide 213
