Adding Peripherals to a System
Adding a Peripheral to Any System
After deciding which copied configuration group to modify, use the global module
BASEGROUP command to activate the group:
sysgen>BASEGROUP groupname
Use the I/O configuration contained in CONFNCL1 as an example configuration for this
exercise.
3. Activate the IO configurator.
Enter the global module command, IO, at the SYSGEN prompt to activate the IO
configurator:
sysgen> io
** IO configurator commands **
aclass (ac) adev (ad) apath (ap) avol (av)
dclass (dc) ddev (dd) dpath (dp) dvol (dv)
lclass (lc) ldev (ld) lpath (lp) lvol (lv)
maddress(ma) mclass (mc) mdev (md) mpath (mp)
mvol (mv)
clear (cl)(c) exit (ex)(e) help (he)(h) hold (ho)
oclose (oc) redo
io>
4. Obtain I/O configuration listings.
Enter LCLASS, LDEV, and LPATH, at the IO configurator prompt to get current I/O
configuration listings:
io>LCLASS DEST=OFFLINE
io>LDEV DEST=OFFLINE
io>LPATH DEST=OFFLINE
io>OCLOSE
The OCLOSE command closes SYSGEN’s listing file, SYSGLIST, and prints the
information in the file.
Refer to Chapter 5 , “Modifying Input/Output (I/O) Configurations,” for more
information on using the LCLASS, LDEV, LPATH, and OCLOSE commands.
5. Decide on which LDEV to add the drive.
View the LDEV command output. Choose any unused LDEV and consider assigning it to
the disk drive. For this example, use LDEV 14.
6. Decide on the class of the added peripheral.
