hi, all, please correct me if I am wrong. can Ultra160 HD run on Ultra2 Controller with Ultra2 speed?! I tried to put Ultra160 HD (Seagate 9G HD) on a Ultra2 controller (Adaptec 3896N), the SCSI BIOS detect the drive without errors. when I tried to install RedHat 6.1 (2.2.12) or Mandrake 7.0

suggested changes to raid tools

2000-04-02 Thread Michael Robinton
I'm in the process of upgrading another production system from old tools to new and noticed that you can't do a "raidstop" unless there is a valid raidtab. It seems to me that with a persistent superblock, this should not be necessary. The same applies to raidstart. Unless there is some

Copying partition information

Hi all, Is there an easy way to copy the partition information from one disk to another disk that is exactly the same size? I'm guessing a dd on the right device might do this but the exact command would be appreciated. My goal is to not have to manually fdisk multiple disks
