Preparing the Command Module
Set the Host IDs on the Controllers
12 MetaStor Command Module Installation Guide Revision A, March 1998
Set the Host IDs on the Controllers
Tools/Equipment
Antistatic wrist strap, shunts (supplied with unit), and needle-nose
pliers
Instructions
Every device attached to a SCSI bus or Fiber Channel network must
have a unique ID number in order to communicate. Before shipping
a rackmount or deskside command module, the manufacturer sets
the controller host IDs to the following:
●
Controller A, host ID 5
●
Controller B, host ID 4
If these host ID numbers conflict with other devices on your system,
use the following procedure to change the host IDs.
1 Put on an antistatic wrist strap or other protective device.
CAUTION
Electrostatic discharge can damage sensitive components. Use a
grounding wrist strap or other antistatic precautions before
removing or handling any components in the cabinet.
2 As necessary, change the controller host ID settings ( Figure 5 ).
Look on the back of the command module in the upper right corner for
rackmount models; the upper left corner for deskside models. There are
sixteen pins, eight per controller, that determine the hosts ID numbers.
To change an ID number, install or move jumpers to the appropriate
pins. Use needle-nose pliers to remove the jumpers, if necessary.
