Support For Speed Auto-Negotiate - HP 316095-B21 - StorageWorks Edge Switch 2/24 Release Note

Support for speed Auto-Negotiate

Auto-negotiate is supported. However, HP recommends that the port speed for E_Ports (for Interswitch
links, or ISLs) be set to a specific port speed (1Gb/sec, 2Gb/sec, or 4GB/sec as appropriate for the
speed of the Directors or Edge Switches being connected) instead of to Negotiate. Using a specific
port speed decreases the time for a fabric build in response to some perturbation event in the fabric.
Similarly, setting a specific port speed for N_Ports also decreases fabric build time. However, setting a
specific port speed for N_Ports is not required.
There are a few older HBA devices that do not always succeed in logging in to a switch port when
the port speed is set for auto-negotiate.
Workaround
If an older HBA has difficulty logging into a switch port that has its port speed configured as Negotiate,
configure that port speed to 1Gb/sec, 2Gb/sec, or 4GB/sec according to the operation speed of the
HBA connected to that port.

Determining current version
This section describes how to determine the current version of firmware for an Edge Switch or Director
using the HAFM, HAFM Basic, or CLI.
Using HAFM
To determine the current version using HAFM:
1. Open the Element Manager for the Edge Switch or Director.
2. Select Product from the menu bar.
A menu appears.
3. Select Properties.
The firmware version appears in this dialog box.

Workaround
The firmware should not accept a blank key.The RADIUS
key should not be blank. Ensure that you enter the key
correctly.
Temporarily disable CT authentication, and then
activate the zone set.
