Known Issues HSG80 Transparent Mode Not Recommended with Controller in SCSI-3 Mode with HP-UX Operating Systems Due to an issue with non-existent 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, Version 3.0. 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 server 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, which can be cleared 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). Disconnecting the Null Modem Cable Always log out and disconnect the Null Modem cable from the serial maintenance port when not in use or when the switch is reset. 8 director release notes
