Setting the Loop ID to Provide Additional Loop IDs
If Feature Switch 3 on the Ultrium Tape Drive is set to
ON
(see
1
in Figure 6 on
page 16), the LID/status connector
2
has the following definition:
v
Pins 1 through 7 are used to set the LID.
v
Pin 8 overrides pins 1 through 7. If pin 8 is jumpered, the drive will use its vital
product data (VPD) to set the AL_PA. The enclosure can set the AL_PA in VPD
through the RS-422 interface.
v
Pin 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 4 for its
corresponding LID.
2. Locate the LID/status connector on the drive (see
2
in Figure 6 on page 16).
3. Jumper pins 1 through 8 as shown in Table 4.
Table 4. ID Settings that Provide Additional Loop IDs. The table lists the LIDs, corresponding AL_PAs, and definitions
of the jumpers on the connector pins. Feature Switch 3 must be set to
ON
.
