Some customer environments use application or host software that is affected by the restart of the director CTP during a HotCAT download operation. Applications that rely on inband management servers are especially prone to problems caused by processor restart. For example, an application may be configured to poll the director or switch at regular intervals. The polling process could occur during a restart period, causing the application software to react adversely. As a solution, shut down those applications driving inband requests during a firmware upgrade, then restart the applications after upgrade completion. Upgrading firmware on an edge switch from 04.xx.xx to 05.xx.xx An issue has been identified in release 04.xx.xx if the contents of the nonvolatile storage (NVRAM) on the CTP become corrupted. Once the configuration has been loaded, this corruption is not detected until an IPL/IML, power cycle, or firmware code load. If the NVRAM in the CTP has corrupted contents, the firmware load can cause the configuration to reset to factory defaults, which could cause a system outage. Edge switch products already running 05.01.00 or later continually validate the NVRAM configuration, so risk of an outage is extremely low. For edge switch products running an earlier version of firmware, the risk of an outage increases due to the NVRAM issue. If an outage compromises system integrity, HP recommends that the edge switch firmware upgrade be a scheduled maintenance action that anticipates the failure of switch connectivity. This issue was corrected with firmware 05.02.00-13 and later. To safely upgrade firmware on a edge switch, perform the following: 1. Upgrade HAFM software on the HAFM server/appliance to 07.01.00 (minimum). 2. Download firmware 05.02.00-13 using the Firmware Library option under the Product Manager Maintenance menu. 3. Back up the edge switch configuration using the Backup & Restore Configuration option under the Product Manager Maintenance menu. 4. Upgrade the firmware to 05.02.00-13 on each edge switch using the Send option on the Firmware Library dialog box. Upgrading firmware on a director from 04.xx.xx to 05.xx.xx An issue has been identified in release 04.xx.xx if the contents of the nonvolatile storage (NVRAM) on the active CTP become corrupted. Once the configuration has been loaded, this corruption is not detected until an IPL/IML, power cycle, or firmware code load. If the NVRAM in the active CTP has corrupted contents, the firmware load can cause the configuration to reset to factory defaults, which could cause a system outage. By using the following procedure to upgrade firmware, configuration is preserved and a system outage is avoided. This issue was corrected with firmware 05.02.00-13 and later. 10

Upgrading
fi
rmware on an edge switch from 04.xx.xx to 05.xx.xx
An issue has been identi
fi
ed in release 04.xx.xx if the contents of the nonvolatile storage
(NVRAM) on the CTP become corrupted. Once the con
fi
guration has been loaded,
this corruption is not detected until an IPL/IML, power cycle, or
fi
rmware code load.
If the NVRAM in the CTP has corrupted contents, the
fi
rmware load can cause the
con
fi
guration to reset to factory defaults, which could cause a system outage.
Edge switch products already running 05.01.00 or later continually validate the NVRAM
con
fi
guration, so risk of an outage is extremely low. For edge switch products running an
earlier version of

rmware, the risk of an outage increases due to the NVRAM issue. If
an outage compromises system integrity, HP recommends that the edge switch
