Hello. I ordered three 9.1gb hot swapable scsi drives for my linux server. The server had 1 drive, now has 4. I am having some trouble finding them in /dev -- It is not RAID. Upon startup, the SCSI card shows somthing similair to: Channel B SCSI ID#0 - drive (original with O/S) SCSI ID#1 - drive SCSI ID#2 - tape backup SCSI ID#3 - drive SCSI ID#4 - drive I found the guide @ the bottom of the post and read it over. But I don't want to mess up and format my O/S. My drives are on scsi channel B, but 'df' shows: Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda2 8001052 4767188 2827420 63% / /dev/sda1 101089 14274 81596 15% /boot none 159812 0 159812 0% /dev/shm Also when I boot up I get these errors: Oct 8 17:57:43 ibm2 kernel: I/O error: dev 08:21, sector 0 Oct 8 17:57:43 ibm2 last message repeated 2 times Oct 8 17:57:43 ibm2 kernel: I/O error: dev 08:21, sector 64 Oct 8 17:57:43 ibm2 kernel: I/O error: dev 08:22, sector 0 Oct 8 17:57:43 ibm2 last message repeated 2 times Oct 8 17:57:43 ibm2 kernel: I/O error: dev 08:22, sector 64 Oct 8 17:57:43 ibm2 kernel: I/O error: dev 08:23, sector 0 Oct 8 17:57:44 ibm2 last message repeated 2 times Oct 8 17:57:44 ibm2 kernel: I/O error: dev 08:23, sector 64 So where in /dev are my 3 harddrives I plugged in? Is that error mean they are not working. Thank you for any help! -Gian Guide I read: >> >> >> Re the linux side of it: #fdisk /dev/sdb to partition it #mkfs -t ext2 /dev/sdb1 to format it #mkfs -t ext2 -j /dev/sdb1 for ext3 or #mkfs -t reiserfs /dev/sdb1 for ReiserFS Then add to /etc/fstab #/dev/sdb1 /mnt/mountpoint ext3 default 2 1 where /mnt/mountpoint is a folder you have already created. NB The last 2 digits of this line refer to whether the drive will be checked for integrity (fschk/scandisk) and included in a backup. Make sure that the entry is terminated with a carriage return else it will be ignored. If everything is ok you should be able to #mount /mnt/mountpoint and receive no error messages. Good luck!=o) >> >> Warm Regards, Gian Spicuzza

I am an idiot. I found the drives.../dev/sdb,c,d as usual (it's been a long day). But what explains those I/O errors? Warm Regards, Gian Spicuzza
