HP AARTDZHTE/958000284008 manual Support for speed Auto-Negotiate

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 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 is physically removed between directors or switches, the Fibre Channel Adapter model FCA2354 transmits a Not Operational 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 operation 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 Hardware View, click the port 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 specific port speed (1Gb/sec or 2Gb/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.
