HP StorageWorks Fabric OS 5.2.0b Release Notes (AA-RWEYB-TE, February 2007)

Fabric OS 5.2.0b updates
The following sections list important updates.
At startup — FC link connection shows G-Port status
Under c er tain circumstances, with some switches running 5.2.0x (HP StorageWorks 4/8
or 4/16 SAN Switch, HP StorageWorks 4/32 SAN Switch, HP Storageworks 4/64
SAN Switch and HP StorageWorks 4/256 Director) connection to the SAN may not be
established due to switch port showing G-Port status.
Manual recovery from this event can include the following actions in order of severity of
impact until the problem no longer occurs:
• Action 1: From the switch, issue portDisable [port_num]
wait a few (5-10) seconds and then issue portEnable [port_num].
It may take one to two minutes following the portEnable command for the
device to successfully login.
If it fails, use the portDisable/portEnable sequence three to five times
before proceeding to Action 2.
• Action 2: Disconnect the FC cable from the switch. Wait approximately 30
seconds and reconnect. If this fails to resolve the G-Port issue after a few
attempts, go to Action 3.
IMPORTANT:
Try the actions listed (1 and 2 above) first. The thre e actions described next are
intrusive to the switch.
• Action 3: Reboot the EVA c ontroller with the G-Port condition. Or, if an HBA,
reboot the host with the G-Por t condition. If this fails to resolve the G-Port issue,
go to Action 4.
• Action 4: Perform a switchDisable/switchEnable sequence, one time
only. If this fails to resolve the G-Port issue, go to to Ac tion 5.
• Action 5: Reboot the switch.
Potential problem prevention for the G-Port status issue
You may want to lock the port speed to match the device spee d, and force the port
type to an F-Port.
For example, the following commands show how to lock port 7 on a non-bladed 4Gb
switch to a port speed of 2Gb, and how to disable port 7 from becoming an E-Port, and
forcingittofunctionasanF-Port.
