XTCC Emulations of SCSI drives (VTD)
A dashed line indicates that the host adapter and/or emulation are not ready.
If no line is displayed, no LUN was found.
8.11.2 FC-SCSI host adapter functions
8.11.2.1 Perform Link Down/Up Sequence
For approx. 30 seconds the status “Link Down” is generated, thus activating a flashing dis-
play on the module. This enables the module to be located in the hardware.
The function can be called only if the host adapter is in “ACTIVE” mode.
8.12 Emulations of SCSI drives (VTD)
8.12.1 Object information on emulations of SCSI devices
The emulation type VTD (Virtual Tape Device) is provided for open systems (OS).
Each emulation is assigned to a virtual tape drive. It is represented by a block connected to
the host adapter. Within the block, the emulation type (VTD), logical unit number (0x00,
0x01, etc.), and the number of the virtual drive (V000, V001, etc.) are displayed.
This type of emulation consists of a single process, the status of which is indicated by the
colors pink (stopped), green (running), and green/brown (running with the trace switched
on).
