Setting the Loop ID to Provide Additional Loop IDs

If Feature Switch 3 on the Ultrium 2 Tape Drive is set to ON (see		in Figure 6 on
page 20), the LID/status connector	has the following definition:

vPins 1 through 7 are used to set the LID.

vPin 8 overrides pins 1 through 7. If you place a jumper on pin 8, the drive uses its vital product data (VPD) to set the AL_PA. A tape library can set the AL_PA in VPD through the LDI interface.

vPin 9 is ground.

Note: Feature Switch 3 does not support LEDs on an enclosure. Therefore, when Feature Switch 3 is set to ON, the drive can report Fibre Channel problems (error codes 8 and F) on the single-character display, but not by using the enclosure’s external indicators.

To set the AL_PA:

__ 1. Determine an unused AL_PA address for the drive and refer to Table 6 for its corresponding LID.

__ 2. Locate the LID/status connector on the drive (see in Figure 6 on page 20).

__ 3. Place jumpers on pins 1 through 7 as shown in Table 6 or on pin 8.

Table 6. ID settings that provide additional Loop IDs. The table lists the AL_PAs, corresponding LIDs, and definitions of the jumpers on the connector pins. Feature Switch 3 must be set to ON.
