On the target system, start a TACL session and log on as a super-group user.
3.1 Record Current SYSnn Subvolume
1. At the TACL prompt:
> STATUS *, TERM, PROG
2. Record the SYSnn subvolume on Worksheet 1.
3.2 Check Storage Automatic Configuration and Autostart
It is recommended that you start an SCF log file to track all configuration changes
made during the system expansion.
1. Start SCF and enter the following command:
-> INFO SUBSYS $ZZSTO
You will see something similar to the following display:
In this display:
•
AutoConfigure is ON, which indicates that the Storage Automatic Configuration
feature of this system is on.
•
AutoStart is OFF, which indicates that the Autostart feature of this system is off.
If you set both the Storage Automatic Configuration and Autostart features of your
target system to ON, all internal disk drives in that block are automatically
configured and started when you add the block to your system.
2. If Step 1 shows that either AutoConfigure or AutoStart on the target system is OFF,
enable these features by entering the following SCF command:
-> ALTER SUBSYS $ZZSTO, AUTOCONFIG ON, AUTOSTART ON
For additional information about the Storage Automatic Configuration and Autostart
features of internal disks, see the SCF Reference Manual for the Storage
Subsystem.
