whats the difference among these mstm tool cmd?

[thebeatlesguru]

i find in mstm tool there are three cmd:verify,diagnose and exercise , i dont know the difference among there cmds, for example i wanna know whether a harddisk is good or not,which cmd i should use ?

I don't usually use these too much, as there are other tools.

Information: Generate an information log for a selected device
Verify: Pass/fail test of hardware's usability
Diagnose: error isolation test to the FRU level
Exercise: Stress test of the target hardware

(this was from the help in xstm)

FOr the disk you could use any of the tools.

You could also use this to test
# dd if=/dev/rdsk/cxtydx of=/dev/null

Hi,

I prefer to use xstm - the GUI stm.

Just export your DISPLAY & run

xstm &

It's a lot more intuitive. Just find the device in the display, highlight it & pull down the menu you want to select the desired action.

Rgds,
Jeff

HP CE's depend on LOGTOOL, which is a part of STM, and it???s from them that I've learned how to use it. Since then I find it to be the most reliable hardware evaluation utility in HP-UX:

STM > TOOLS > UTILITY > RUN > LOGTOOL > FILE > VIEW > RAW SUMMARY.

Note the first and last dates of transactions and calculate the difference. If the difference is short, like 4 hours, then this is important to note. Now read down the report of hardware addresses and observe the integer numbers in parenthesis. Anything over 150 in this 4 hour period should be called into HP for replacement. It???s this simple.

For disks, as mentioned above, use the dd command:

??????dd if=/dev/dsk/c5t6d0 of=/dev/null count=1000000??????

With ???..dd?????? its important to have a high enough count to get passed the disk buffer cache.

I prefer to use the ascii STM mode ie cstm instead and I suggest you go through the cstm tutorial below to get familiarize with it ..
http://www.docs.hp.com/cgi-bin/otsearch/getfile?id=/hpux/onlinedocs/diag/stm/stt_ccomm.htm&searchterms=cstm&queryid=20030312-202456
As for the the tool the one you need to run is the "exercise" command within cstm. What it does is it'll run stress test on the hardware that you select. So if you decide to run this on your hard disk you might want to wait till the system is less busy before doing that. Example ..
# cstm
cstm> map
cstm> sel dev
cstm> exercise
At this point the exercise tool will begin running. To see the status (ie if it has completed or not) run ..
cstm> map
and you'll eventually see "Completed". To view the log file you would run ..
cstm> eal
cstm> efl
At any time you can usethe help command in cstm to get more information of the command you're using. For example ..
cstm> help
cstm> help exercise
