HP StorageWorks Director and Edge Switch Release Notes (09.09.08) (5697-0720, October 2010)

2. Download firmware 05.02.00-13 by selecting Firmware Library from the Product Manager

Maintenance menu.

3. Back up the Director configuration by selecting Backup & Restore Configuration from the Product

Manager Maintenance menu.

NOTE:

Step 4 is not required if you are upgrading from 05.xx.xx or later.

4. Using the Product Manager, execute a CTP swap:

a. From the Product/Element Manager Hardware view, verify that the amber LED is not illumin-

ated for either CTP card.

b. Right-click the CTP card that you believe is active, and then select FRU Properties. Verify that

this 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 firmware 04.xx.xx if the contents of the NVRAM on the CTP are

corrupted. Once the configuration has been loaded, the 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 the 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

Edge Switches or Directors are not required to be offline before performing a firmware downgrade

operation. Limitations to performing a downgrade are clearly identified.
