Reinstalling feature licenses

Feature licenses (or keys) must be reinstalled after performing a factory reset on an Edge Switch or

Director to regain use of the licensed features (for example, SANtegrity Binding).

CTP controls port lights

Port lights on the Edge Switches and Directors are controlled by the CTP. Certain activities such as

ﬁrmware updates, IPLing the CTP, or switching over to the backup CTP (Director) can cause these port

lights to extinguish momentarily until control is reasserted by the CTP. The actual Fibre Channel trafﬁc is

not affected during these times.

Full-fabric capability for Edge Switch 2/12

Unlike other Edge Switch and Director products, a PFE key controls Edge Switch 2/12 E_Port-to-E_Port

connections. After purchasing and installing the feature key, you can conﬁgure for E_Port connections on

any of the active ports.

The feature key includes distance support. With ﬁrmware 06.00.00 and later, the Edge Switch 2/12

ships with ﬁve BB_credits allocated to each port. After activation of the Full Fabric feature on a switch,

each port has 12 BB_Credits allocated to support up to 12-km links at 2-Gb/s speed.

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.

Table 6 ﬁrmware 09.02.00 known issues

Issue

For the Director 2/64 in a FICON environment,

when a QPM is swapped for an XPM, or an

XPM is swapped for a QPM, the PDCMs of the

affected ports are not cleared. PDCMs cannot be

conﬁgured via HAFM after this happens.

For Edge Switches, the alias database persists after

a conﬁguration reset, where it should be cleared.

Attempts to activate a large zone set through OSMS

when CT authentication is enabled occasionally

may not be successful.

Workaround

Do not immediately replace a QPM port card with an

XPM port card, or an XPM port card with a QPM port

card. To make this change, remove the ﬁrst port card

(QPM or XPM), install a UPM port card temporarily (for

two minutes), and then remove the UPM and install the

desired port card (QPM or XPM).

Alias Database can be successfully cleared through CLI

and EFCM basic.

Temporarily disable CT authentication, and then

activate the zone set.
