Converting a Single-System Conﬁguration to a DSSI VAXcluster Conﬁguration

C.1 Securing the DECarray for Conversion

Once the host systems have been correctly brought down, perform the following

steps:

1. Take each ISE installed in the DECarray off-line.

a. For all SF7x storage enclosures, press all OCP Ready buttons to their

out position.

b. For all magazine tape ISEs, press the Load/Unload button. Wait until

the cartridge is returned to the magazine and the In-Use LED is

extinguished.

2. For all SF7x storage enclosures, press all drive dc power switches to their

out position.

3. For all SF7x storage enclosures and magazine tape ISEs, turn the ac power

switches located at the rear of each to their 0 or off position.

4. At the rear of the DECarray, turn the power controller circuit breaker off.
