DELL Poweredge 1800

There are only 2 ways I know of to silence the percs warning alarm. 1st is openmanage and the 2nd is in the perc bios.

how to do using perc bios?

enter the controller bios by pressing ctrl+m while the controller is loading then go to objects-> adapter-> choose the adapter-> alarm control-> silence alarm.

Yah but it shows "fail" then when i click on it shows no hard disk there so i do not have options there to disable alarm

What are you clicking on? There is no mouse in the bios, to enter the perc bios you will need to restart the server and while the controller is loading press control+m. In openmange you right click on the controller and go to options and disable the alarm. Also fixing the problem like replacing a failed drive and rebuilding will also silence the alarm.

Can i reuse the crashed harddisk by deleting every thing as use it as new? i did not mean click i meant choose that option, so my problme now that i have failed harddisk and that is why the beeb still running, if possible to delete it and attach it again that would be great so i can use it again, also if that is possible, can i use it as hotspare in case another harddisk fail in the future?

Thanks

If you are using a PERC 4 of some kind, you can silence the alarm in the PERC BIOS (CTRL_M) under Objects, Adapter, Alarm Control.

You may be able to use your "failed" disk ... it is not always a "bad" disk that causes it to fail.  If you have hot-swappable drives, you can try to rebuild it in Objects, Physical Drives, Enter on the failed drive, and Rebuild, or you can try to simply reseat the drive.  I would test the drive before attempting to rebuild it.  You can use the 32-bit diagnostics (available from support.dell.com) or the F10 diagnostics on the drive, or you can test it from Windows using the Online/PowerEdge Diagnostics.  If it fails, throw it away.  If it passes, then attempt a rebuild.  If it doesn't rebuild, you have other problems.
