Hi,
On P5 I would like to add hard drive, currently 2 hard disk are already exists, would like to add one more,
2 Slots are emtpy, I would like to know how to find out wheather adapter is attached to that 2 free slot using command.
Not possible... If there is no real device connected it is not shown in system.
What is type model of your server and extention drowers if you have any?
Thanks Gito for Prompt Response,
System Model is IBM,9131-52A.
According documentation
IBM Redbooks | IBM System p5 520 and 520Q Technical Overview and Introduction
You should have internal dual scsi controller already connected with both channels to your backplane.
Dear,
In unix systems you hav a tool for managing the server use it.
smitty
Not in all UNIX systems though. SMIT or smitty is available only on AIX and it's IBM proprietary 
AND he is using AIX as you can see....
Juri_al :
Can you tell me how to check using smitty if SCIS/SAS adapter is connected to backplain ?
With multiple commands like lsdev, lscfg, lsattr lsslot you can check connected device but SAS cable or even backplain split is not recognized as device. You can not check that without a checking documentation or in some cases some person is needed to do checking.
