Hi Aqeel,
Use to have some, might be at home, might be the previous HACMP can't remember... but I shouldn't say you should focus on it at all...
Go through the HACMP Certification redbooks and know your stuff. I got some test years back, glimpsed at it and just decided that it's not the road I'm going to take.
In the test they have various different LONG questions so it's anywaz impossible to remember. Bottom line, know HACMP. It's the purpose of writing the test right. To certify and also prove to yourself that you are on that level.
I'd say for this test, know
AIX, HACMP, some problem resolution, backup & recovery and performance - but the first two are the most important.
Good luck!
