11/21 - RL01/02 PERFORMANCE EXERCISER
ABSTRACT :
The program tries to simulate a user environment. It will randomly exercise up
to 2 controllers and 8 drives. Initialy the bad sector file is read from each drive
and stored in memory, then each pack is written with one of eight data
patterns. The drives are randomly picked and given a random string function of:
1. seek, write, write-check
2. seek, read data, compare data
3. seek, read headers, read 1 sector with no header compare, get status
4. seek, read, read
OPERATING PROCEDURES :
.R NRLKA0
This program is running under the supervisory program.
This supervisory program will first talk to you.
DR>START<CR>
You have to answer the hardware questions.
This is a (mostly used) example :
Change HW (L) ? Y<CR>
# UNITS (D) ? 2<CR>

(this is the number of drives)

UNIT 0<CR>
RL11 (L) Y ?<CR>
BUS ADDRESS (O) 174400 ? <CR>
VECTOR (O) 160 ? <CR>
DRIVE (O) 0 ? 1 <CR>
DRIVE TYPE = RL01 (L) Y ? N
BR LEVEL (O) 5 ? <CR>
UNIT 1
........
Change SW (L) ? N<CR>
to get a summary type <CONTR C>
DR>PRI
after the summary, to continue type
DR>CON
If you answer Y to the question
CHANGE SW (L) ? Y <CR>
you can change a lot of parameters like
RETRY LMT (D) 1 ?
TIME BETWEEN REPORTS (MIN) (D) 240 ?
