A5675A DS2100 DISK ENCLOSURE - MAX=4 DISKS PER ENCLOSURE - MAX=3 ENCL.

Apparently this device holds up to 4 disks.

ioscan -fnC disk

You will see three disks with the same model number that are already in your DS2100 disk enclosure. Search for that type of disk or post the ioscan information and I or someone else will help you find them.

Jose,

since you have a SCSI RAID4si controller to manage the disks you cannot just enlarge your current LUN by a fourth disk.

You will have to backup your data, umount filesystems, vgexport the volume group, insert the new disk, destroy the current 3 disk RAID5 LUN, create a new 4 disk LUN, recreate a volume group and logical volumes on that LUN, create filesystems, mount them, restore your data.

Bernhard
