Release Notes for Cisco SN 5428-2 Storage Router, Release 3.5.1
OL-5241-02
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.
