C.2 Conversion Procedure

This section contains the steps to do the following:

• Convert an Sx72 storage enclosure from split-bus to through-bus mode

(Section C.2.2)

• Convert an Sx300 storage array, cabled for a single-host conﬁguration, that

contains Sx72 storage enclosures, or magazine tape subsystems, or both, to

a dual-host conﬁguration (Section C.2.3)

• Label the cables (Section C.2.4)

Fill out a new conﬁguration sheet (Section C.2.4.1)

Fill out the labels (Section C.2.4.2)

Place the labels (Section C.2.4.3)

• Power up the Sx300 storage array (Section C.2.5)

• Bring the new dual-host conﬁguration back on-line (Section C.2.6).

• Verify the operation of the converted Sx300 storage array (Section C.2.7)

Follow each step in the order presented.

C.2.1 Through-Bus to Split-Bus Conversion

1. Do the following if you are installing an SF7x in split bus mode (single-host

only) (see Figure C–2):

CAUTION

To maintain stability, extend only one SF7x storage enclosure or

magazine tape subsystem on the slide mounts at a time.

a. Loosen the four captive slide assembly screws. Slide the inner assembly

out until the drawer locks in the service position.

b. Push the inner assembly forward from the rear.

Note

Do NOT completely remove the SF7x inner drawer assembly from the

extrusion tube and extend only one at a time.
