Re: Array Controller 641 Problem,

Dear Mahmood,

Its looks like a cabling problem.
The Smart array controller never show the exact disks at detection, just rolling "-" signs.
If you see the detection of hard drives, then somebody connect the hot plug HDD bay to the on-board SCSI controller, not to th Smart Array controller.
Check at POST, if you can see exatly the disk detection. the solution is simple:
- Turn off the server, pull out power cord
- take a look into the server
- there is a SCSI cable, from behind the disk cage to the motherboard SCSI connector
- disconnect it from motherboard and connect it to Smart Array 641 (it has only one SCSI connector)
- beware, not to broke the pins of the connector
- you dont need any extra terminator for SCSI devices in this situation (its build into the cage and controller), so dont try to find it
- plug in the power and at boot, you will see, the controller want to make a default RAID 5 from disks. Accept it or just skip this step at POST (power on self test).

After that you can easily configure your RAID arrays under Smartstart.

Re: Array Controller 641 Problem,


Thank you very much and I really appreciate your help,

You are right, after troubleshooting the server I found that my colleague did not fix the SCSI cable to array controller in the right way, so I put little pressure and its work fine.

Best regards,
