-s
n
Specifies n as the number of memory segments. The
default (and maximum) number of segments is 3.
The following example tests the default number of memory segments, each
with a default segment size:
# shmx &
The following example runs three memory segments of 100,000 bytes for
180 minutes:
# shmx -t180 -m100000 -s3 &
F.1.6 Exercising a Disk Drive
Use the diskx command to exercise the disk drives. The main areas that
are tested include the following:
• Reads, writes, and seeks
• Performance
• Disktab entry verification
_____________________ Caution _____________________
Some of the tests involve writing to the disk; for this reason, use
the exerciser cautiously on disks that contain useful data that
the exerciser could overwrite. Tests that write to the disk first
check for the existence of file systems on the test partitions and
partitions that overlap the test partitions. If a file system is
found on these partitions, you are prompted to determine if
testing should continue.
You can use the diskx command flags to specify the tests that you want
performed and to specify the parameters for the tests. For more
information, see the diskx
(8) reference page.
The diskx command has the following syntax:
diskx
[ flags][parameters] -f devname
The -f
devname flag specifies the device special file on which to perform
testing. The
devname
variable specifies the name of the block or character
special file that represents the disk to be tested. The file name must begin
