4.
Using the Product Manager, execute a CTP swap:
a.
From the Product/Element Manager Hardware view, verify that an amber LED indicator is
not displayed for either CTP card.
b. Right-click the CTP card you believe to be active, and then select FRU Properties. Verify that
it is the active CTP card.
c. Right-click the active CTP card, and then select Switchover.
The Director loses its Ethernet connection for a short time during the switchover process.
When switchover occurs, the green LED illuminates on the backup CTP card to indicate that
it is now the active card.
5. Upgrade the firmware to 05.02.00-13 on each Director by selecting Send in the Firmware Library
dialog box.
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 NVRAM on the CTP are 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 on the CTP has corrupted contents, the firmware load can cause the
configuration to reset to factory defaults, which can 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 has been resolved with firmware 05.02.00-13 and later.
To safely upgrade firmware on an Edge Switch:
1. Upgrade HAFM software on the HAFM Server/Appliance to 07.01.00 (minimum).
2.
Download firmware 05.02.00-13 by selecting Firmware Library from the Product Manager
Maintenance menu.
3. Back up the Edge Switch configuration by selecting Backup & Restore Configuration from the Product
Manager Maintenance menu.
4.
Upgrade the firmware to 05.02.00-13 on each Edge Switch by selecting Send in the Firmware
Library dialog box.
Considerations for downgrading the firmware version
Directors or Edge Switches are not required to be offline before performing a firmware downgrade
operation. Limitations to downgrades are clearly identified if there are any reasons for not performing the
operation.
Before downgrading firmware, HP recommends that you back up the Director or Edge Switch
configuration. Refer to the Director or Edge Switch Element Manager user guide for more information.
EWS (HAFM Basic) also provides an option to print or save product configuration to a file. See the HAFM
or EFCM Basic user guide for more information.
Consider the following when downgrading firmware:
• All installed QPM cards must be removed from the Director 2/140 if downgrading to a version
earlier than 09.00.00. All installed QPM cards must be removed from the Director 2/64 if
downgrading to a version earlier than 09.01.00.
• All trial PFE key features must be disabled before downgrading to a version earlier than 09.00.00.
• The domain ID offset must be set to the default value of 0x60 before downgrading to versions
earlier than 09.00.00.
• WWN Aliases will be disabled when downgrading firmware in any Edge Switch or Sphereon
switch to a release earlier than 09.01.00.
• Downgrading directly to a release prior to 08.xx.xx from 09.06.02 is not allowed. To downgrade
to a release prior to 08.xx.xx, you must first downgrade to 08.02.00.
