Upgrading to the AsyncOS 7.7 Release
Warning If you are upgrading from AsyncOS 7.2.1 or earlier and you have M160 hardware:
You may need to upgrade the hard drive firmware before you upgrade the
AsyncOS. To verify whether or not your M160 requires the firmware upgrade, run
the upgrade command at the command line prompt. If the M160 requires the
firmware upgrade, “Hard Drive Firmware upgrade (for C/M/S160 models only,
build 002)” will be listed as an upgrade option. If listed, run the firmware
upgrade, and then upgrade AsyncOS for Security Management to version 7.2.2.
See the Cisco IronPort Hard Driver Firmware Upgrade for C160, S160, and M160
Appliances Release Notes on Cisco.com for more information.
