When to Use This Section

This section provides an overview of operating, monitoring, and recovery operations for tape drives attached to Integrity NonStop NS-series servers.

Overview of Tape Drives

A new generation of multimode fibre channel (MMF) peripherals is supported on Integrity NonStop systems. Tape drives with an MMF interface are connected directly to a fibre port on an FCSA in an IOAME or VIO enclosure. Some high voltage differential (HVD) SCSI drives are also supported in the NS optical environment. These drives are connected using an M8201 fibre channel to SCSI router. The M8201 converts the FCSA MMF connection into two SCSI buses. Currently, only optical port 0 is used on the M8201. The SCSI drives are connected using 68-pin to 68-pin HVD SCSI cables. These cables have a high density connector for the M8201.

Most drives supported on NonStop S-series can be connected to an Integrity NonStop NS16000 server through an IOMF2 in an IOMF enclosure. The drives can be interfaced in the same manner that is supported in S-series, either through an SNDA or a SCSI port on an IOMF2 board. OSM provides different views for drives that are connected through an FCSA versus an IOMF2. See Monitoring Tape Drives on
