Pedro, The drive information you are seeing is the Virtual Disks. You can install OpenManage on the server to see the Physical levels, You may need to reboot though.  Open Manage - www.dell.com/.../poweredge-r510 Another thing you can do is go to this link and then go to SYSTEM CONFIG tab, then click CURRENT CONFIGURATION, then click on ANALYZE SYSTEM - www.dell.com/.../poweredge-r510 It should tell you the drives installed.
Hello! We have a Dell PoweEdge R510 with Perc H700 RAID controller. We would like to add more disks to the RAID and need to know the disk model to buy similar ones. Is it possible to check that without turning the machine off and remove the disk? We have Citrix XenServer installed and already tried some linux commands. With  cat /proc/scsi/scsi, I got the following info, but nothing related to the hard drive model: Attached devices:Host: scsi0 Channel: 00 Id: 32 Lun: 00  Vendor: DP       Model: BACKPLANE        Rev: 1.10  Type:   Enclosure                        ANSI  SCSI revision: 05Host: scsi0 Channel: 02 Id: 00 Lun: 00  Vendor: DELL     Model: PERC H700        Rev: 2.10  Type:   Direct-Access                    ANSI  SCSI revision: 05Host: scsi3 Channel: 00 Id: 00 Lun: 00Also tried hdparm -I /dev/sda but with no luck.  Thanks for your help! Pedro
