Chapter 2. Installing a single storage system on a SCSI bus
Connecting the asynchronous (console) cable
To bind disk modules into physical disk units, set up storage-system caching, and
monitor storage-system operation using
dassmgr , you must connect the console port
on the SP to an asynchronous port on the server. If you are installing a dual-initiator
configuration, you can connect the console port to only one server.
IMPORTANT The console port on the SP and the asynchronous port of the
server must be configured with the same line characteristics. By default, the
SP’s asynchronous port operates at 9600 baud, even parity, and 1 stop bit.
If the server does not have an available RS-232 port with a 25-pin female connector,
you need to use one of these:
D
25-pin-to-25-pin female-to-female gender changer if the server has a 25-pin male
connector for the RS-232 port
D
25-pin-to-9-pin adapter cable if the server has a 9-pin male connector for the
RS-232 port
To use a gender changer — Start with step 1 in the procedure that follows.
To use an adapter cable — Start with step 2 in the procedure that follows.
If you are not using either a gender changer or adapter cable —
Start with step 3
in the procedure that follows.

To install an asynchronous (console) cable
1. If the server has a 25-pin male connector for the RS-232 port, install a gender
changer on the server’s RS-232 connector.
