![]() Be sure that you understand this principle before formatting any hard disk drive. It may be necessary to put the RAID controller in JBOD mode.įormatting a drive erases all user data. You may also use Seagate's Seatools for DOS to perform a zero-fill, though this tool can sometimes have trouble working with drives that are connected in a RAID configuration. Protect against power failure or other power interruptions during the format. If you do decide to perform a low level format, do not abort the format as this is likely to make the drive inoperable. You do not need to perform another low level format on this drive unless you decide to perform certain diagnostics through the controller. The drive has been low level formatted at the factory. Power is supplied through the SAS connector. There are no jumpers or terminators on the drive. The SAS connector is normally located on a SAS backpanel. This connects the drive directly to your system’s SAS connector. Slide the carrier or tray into the appropriate bay in your host system. SAS drives are designed to be attached without I/O or power cables however, you may also connect the drive using high-quality cables that have a maximum I/O cable length of 4 meters (13.1 feet). You can mount the drive in any orientation. Mount the drive to the carrier or tray provided by the host system using four 6-32 UNC screws. Most SAS host systems provide a way to insert the drive using a carrier or tray, which allows the drive to be hot-plugged into the system. Mount the drive in the host system carrier or tray.Do not apply pressure or attach labels to the circuit board or to the top of the drive.Return the entire drive for warranty replacement service if any part is defective.Do not disassemble the drive doing so voids the warranty.Use caution when troubleshooting a unit that has voltages present.Never use an ohmmeter on any circuit boards. Discharge static from all items near or that will contact the drive. Wear a wrist strap and cable connected to ground. Keep the drive in its antistatic container until you are ready to install it. Drive electronics are sensitive to static electricity.Handle the drive only by the edges or frame. Handling precautions/Electrostatic discharge protection If the controller does not detect the drive, look to confirm that all SAS ports are enabled. Most motherboard setup utilities allow users to disable the SAS ports. See the SAS controller documentation to determine how to assign the drive to an array.Ĭonfirm the SAS channels are enabled. Many SAS RAID controllers require that a drive be assigned to an array before it will allow the operating system to see the drive. Special note for users of a RAID host adapter. Please consult the motherboard or SAS controller documentation for assistance with entering into the SAS BIOS setup. ![]() ![]() If this is the case, the SAS drive will only be displayed in this SAS BIOS message. Some SAS BIOS have a system setup that is not contained within the normal motherboard BIOS. Seagate drive model numbers begin with the letters "ST". As the system starts, the auto-detect feature may display the drive model number on screen. ![]() Most new computers will automatically detect devices through the system setup program (CMOS or BIOS). For additional information about connecting SATA drive to SAS controller, please visit Document ID 006170. What is more, SATA drives can be connected to the same controller as SAS drives if the controller has ports for that (though connecting a SAS drive to a SATA controller will not work). You can use a SAS drive in the same system with SCSI or Serial ATA (SATA) drives as long as both interfaces are supported on the motherboard or with a host adapter. Unlike (Parallel) SCSI, there is no need to set an ID, since each drive connects directly to its own port and since the controller will assign all IDs. Also, depending on the SAS controller, a multi-drive (or "port replicator") cable might be available and useful. With a SAS interface, each SSD has its own cable that connects directly to a SAS host adapter (also called a SAS controller). ![]()
