FW 07.01.02/HAFM SW 08.06.00 HP StorageWorks Edge Switch Release Notes (AA-RTDZH-TE, August 2005)

Workaround
None.
HSG80 transparent mode not recommended with controller in SCSI-3 mode
with HP-UX operating systems
Due to an issue with nonexistent duplicate LUNs being displayed with the HP-UX
operating systems, the HSG80 controller is restricted to SCSI-2 mo d e of operation when
set to Transparent failover mode.
SCSI-3 mo de of operation in Mu ltibus failover mode is fully supported with the use of
Secure Path soft ware, 3.0 or later versions.
Workaround
None.
ISL disconnect causes NOS error with the OpenVMS operating systems
When an ISL connection is physically removed bet ween directors or switches, the Fibre
Channel Adapter model FCA2354 transmits a Not O perational Sequence (NOS)
error. This is observed as an entry in the HAFM appliance Link Incident log for the
port in which the FCA2354 is attached. The director’s Hardware View also displays a
yellow triangle icon over the port that detected this incident. The fabric o peration or
data movement is not disrupted by these incidents, and you can clear alerts from these
incidences using the following procedure.
Workaround
Use these steps to clear the incident alerts.
1. At the HAFM H
ardware View, click the por t module to open the Port Card View.
2. Right-click on the port with the yellow triangle icon, and choose Clear Link Incident
Alert(s).
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 specificportspeed(1Gb/sec or 2Gb/sec,as
appropriate for the speed of the directors or edge switches being c onnected) instead
of to Negotiate.Usingaspecific port speed decreases the time for a fabric build in
response to some perturbation event in the fabric. Similarly, setting a specificportspeed
for N_Ports also decreases fabric build time. However, set ting a specificportspeedfor
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.
