HSG80 transparent mode not recommended with controller in SCSI-3 mode
with HP-UX o perating 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 mode of operation when
set to Transparent failover mode.
SCSI-3 mode of operation in Multibus failover mode is fully supported with the use of
Secure Path software, 3.0 or later versions.
Workaround
None.
ISL disconnect causes NOS error with the OpenVMS operating systems
When an ISL connection i s physically removed between directors or switches, the Fibre
Channel Adapter model FCA2354 transmits a Not Operational Sequence (NOS)
error. This is observed as an entr y in the HAFM appliance Link Incident log for the
port in which the FCA2354 is attached. The director’s Hardware View a lso displays a
yellow triangle icon over the port that d etected this incident. The fabric operation or
data movement is not disrupted by these incidents, and you can clear aler ts 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 port module to open the Port Card View.
2. Right-click on the po rt 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 fabri c. Similarly, setting a specificportspeed
for N_Ports also decreases fabric build time. However, setting 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.
