Review the event browser to determine if excessive port errors are responsible for disabling the port. Look for a message that mentions one of the monitored error types indicating that the port has been disabled, then perform the following procedure: 1. Examine the alarm configuration for the associated error using the show config threshold CLI command. See the show config threshold CLI command in the HP StorageWorks 8/20q Fibre Channel Switch command line interface guide. Are the thresholds and sample window correct? • Yes-Continue • No-Correct the alarm configuration. If the condition remains, continue. 2. Reset the port, then perform an external port loopback test to validate the port and the SFP. For information about testing ports, see the HP StorageWorks 8/20q Fibre Channel Switch command line interface guide or the HP StorageWorks 8/20q Fibre Channel Switch QuickTools switch management user guide. Does the port pass the test? • Yes-Continue • No-Replace the SFP and repeat the test. If the port does not pass the test, contact your authorized maintenance provider. Otherwise continue. 3. Replace the Fibre Channel port cable. Is the problem corrected? • Yes-The procedure is complete. • No-Continue. 4. Inspect the device to which the affected port is connected and confirm that the device and its HBA are working properly. Make repairs and corrections as needed. If the condition remains, contact your authorized maintenance provider. Recovering a switch using maintenance mode A switch can become inoperable or unmanageable for the following reasons: • Firmware becomes corrupt • IP address is lost • Switch configuration becomes corrupt • Password is forgotten In these specific cases, you can recover the switch using maintenance mode. Maintenance mode temporarily returns the switch IP address to 10.0.0.1 and provides opportunities to do the following: • Exiting the maintenance menu (option 0), page 51 • Unpacking a firmware image file in maintenance mode (option 1), page 51 • Resetting the network configuration in maintenance mode (option 2), page 51 • Resetting user accounts in maintenance mode (option 3), page 51 • Copying log files in maintenance mode (option 4), page 52 • Removing the switch configuration in maintenance mode (option 5), page 52 • Remaking the file system in maintenance mode (option 6), page 52 • Resetting the switch in maintenance mode (option 7), page 52 • Updating the boot loader in maintenance mode (option 8), page 52 To recover a switch: 1. Place the switch in maintenance mode by pressing and holding the Maintenance button with a pointed tool until only the Heartbeat LED is illuminated, and then release the button. The Heartbeat LED illuminates continuously when the switch is in maintenance mode. 2. Establish a Telnet session with the switch using the maintenance mode IP address 10.0.0.1. 3. Enter the maintenance mode account name (prom) and password (prom), and press Enter. Switch login: prom Password:xxxx 50

Review the event browser to determine if excessive port errors are responsible for disabling the port. Look

for a message that mentions one of the monitored error types indicating that the port has been disabled,

then perform the following procedure:

Examine the alarm configuration for the associated error using the

show config threshold

CLI

command. See the

show config threshold

CLI command in the

HP StorageWorks 8/20q Fibre

Channel Switch command line interface guide

. Are the thresholds and sample window correct?

•

Yes—Continue

•

No—Correct the alarm configuration. If the condition remains, continue.

Reset the port, then perform an external port loopback test to validate the port and the SFP. For

information about testing ports, see the

HP StorageWorks 8/20q Fibre Channel Switch command line

interface guide

or the

HP StorageWorks 8/20q Fibre Channel Switch QuickTools switch management

user guide

. Does the port pass the test?

•

Yes—Continue

•

No—Replace the SFP and repeat the test. If the port does not pass the test, contact your authorized

maintenance provider. Otherwise continue.

Replace the Fibre Channel port cable. Is the problem corrected?

•

Yes—The procedure is complete.

•

No—Continue.

Inspect the device to which the affected port is connected and confirm that the device and its HBA are

working properly. Make repairs and corrections as needed. If the condition remains, contact your

authorized maintenance provider.

Recovering a switch using maintenance mode

A switch can become inoperable or unmanageable for the following reasons:

•

Firmware becomes corrupt

•

IP address is lost

•

Switch configuration becomes corrupt

•

Password is forgotten

In these specific cases, you can recover the switch using maintenance mode. Maintenance mode

temporarily returns the switch IP address to 10.0.0.1 and provides opportunities to do the following:

•

Exiting the maintenance menu (option 0)

, page 51

•

Unpacking a firmware image file in maintenance mode (option 1)

, page 51

•

Resetting the network configuration in maintenance mode (option 2)

, page 51

•

Resetting user accounts in maintenance mode (option 3)

, page 51

•

Copying log files in maintenance mode (option 4)

, page 52

To recover a switch:

Place the switch in maintenance mode by pressing and holding the Maintenance button with a pointed

tool until only the Heartbeat LED is illuminated, and then release the button. The Heartbeat LED

illuminates continuously when the switch is in maintenance mode.

Establish a Telnet session with the switch using the maintenance mode IP address 10.0.0.1.
