Cisco Systems SN 5428-2 manual Uninstalling an Upgrade, Click Reset System

Page 8

Step 6 At Select next boot version, select the new software version. If you have made configuration changes to the storage router that have not been saved, click the Save unsaved changes? checkbox to save any configuration changes that have been made but not saved to the storage router’s bootable configuration

Step 7 Click Reset System.

Step 8 After the storage router has rebooted, verify that it is running the new software. (See the “Determining the SN 5428-2 Software Version” section on page 7 .)

If the storage router is deployed for transparent SCSI routing, the upgrade to version 3.5.1 from any version prior to 3.3.1 places the storage router in dynamic mode. Dynamic mode resets iSCSI client-to-FC WWPN bindings upon reboots or iSCSI logouts, and requires an intelligent storage array that supports an extended iSCSI FC PLOGI frame. To change the mode of an existing transparent SCSI routing deployment, you must completely clear the storage router configuration. When the storage router reboots, follow the prompts from the initial configuration script to complete the new system configuration and select the desired mode for transparent SCSI routing.

For more information about clearing the storage router configuration, see the section “Resetting the System” in Chapter 11, “Maintaining and Managing the SN 5428-2 Storage Router,” of the Cisco SN 5428-2 Storage Router Software Configuration Guide, Release 3.5.

For more information about static and dynamic modes for transparent SCSI routing, see the section “Summary of Configuration Process” in Chapter 7, “Configuring Transparent SCSI Routing,” of the Cisco SN 5428-2 Storage Router Software Configuration Guide, Release.3.5.

Uninstalling an Upgrade

Note Software versions prior to 3.3.1 do not support the static mode for transparent SCSI routing.
