HP Brocade 4Gb SAN Switch for HP BladeSystem c-Class - Manual (Page 141)

Fabric OS 5.0.0 Advanced Web Tools user guide 141
Firmware download There are multiple phases to firmware download and activation. When
Advanced Web Tools reports that firmware download has completed
successfully, it indicates that a basic sanity check, package retrieval,
package unloading, and verification was successful.
Advanced Web Tools forces a full package install. To perform an
incremental upgrade, use the Fabric OS CLI.
Workaround: A reboot is required to activate the newly downloaded
firmware. This reboot is performed automatically. Although Advanced
Web Tools screens continue to be visible during the reboot, they are not
available. Wait approximately 10 minutes to ensure that all of the
application windows have been restored. If Advanced Web Tools fails
to respond after 20 minutes, you may need to close all Advanced Web
Tools applications windows and restart them, or contact your system
administrator for network assistance.
The Advanced Web Tools loss of network connectivity during a failover
or reboot (initiated though the
firmwaredownload
command) varies
for different configurations:
• Core Switch 2/64 and SAN Director 2/128: loss of network
connectivity is up to 5 minutes if the power-on self-test (POST) is
disabled. If POST is enabled, the loss of network connectivity can
exceed 5 minutes.
• SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32, SAN
Switch 4/32: loss of network connectivity is up to 1 minute if POST is
disabled. If POST is enabled, the loss of network connectivity can
exceed 1 minute.
HTTP timeout You may occasionally see the following message when you try to get
data from a switch or send a request to the switch:
Failed to get switch response. Please verify the
status of your last operation and try again if
necessary.
This indicates that an HTTP request did not get a response. The request
was sent to the switch, but the connection was down, probably caused
by a temporary loss of the web server on the switch. Due to the nature of
an HTTP connection, Advanced Web Tools reports this error after a
90-second default time-out.
Workaround: Verify the status of your last request, using telnet to check
related status, or click the Refresh button from the Advanced Web Tools
application you were working on to retrieve related data. If your request
did not get through to the switch, resubmit it. Executing a refresh from
Advanced Web Tools retrieves a copy of switch data at that moment;
the data you entered can be lost if it was not already committed to the
switch.
