Accusys A16R/A16U-IS Step 2. Mounting the RAID System and Installing Hard Disk Mounting the RAID system The RAID system/Rail Extenders can be installed in a standard 19-inch rack. Follow the procedures below: 1. Attack eight rack nuts into the rack, making sure that they correspond with the mounting points on the rails. 2. Adjust the length of the rails as needed. 3. Secure the rails using two nuts and bolts on both the front and back posts of the rack then tighten the locking screws. 4.
Accusys A16R/A16U-IS Installing the Rail Extenders If the front door was stocked by abstacle chassis at botton side, please follow the procedures below to install the rail extenders. Follow the procedures below to install the rail extenders: 1. Install the rail extenders and attach the screws to secure them. 2. Slide the RAID system into the rack and secure it into place using the fixing screws.
Accusys A16R/A16U-IS Installing the Hard Disks The RAID system supports SAS or SATA interface hard drives. Caution It is recommended to mount the RAID system to the rack cabinet first before installing the hard drives and the drive trays. If the hard drives are installed first, the RAID system may be too heavy to lift or handle. And the possible impact during installation may damage the drives. Follow the procedures below to install hard drives: SAS hard disks 1.
Accusys A16R/A16U-IS 3. Pull open the front panel door. 4. Insert the hard disk trays into the empty slots. 5. Push down the tray handle to secure the hard disk tray into place. 6. Repeat steps 4 to 5 until all the required disks have been installed. 7. Close the front panel door, then lock it.
Accusys A16R/A16U-IS SATA hard disks SATA hard drive installation requires an AA-MUX adapter to be installed on the hard disk tray first before installing the SATA hard disk. Note AA-MUX is an optional accessory and is sold separately. Contact your supplier to purchase one. Follow the procedures below to install SATA hard disks: 1. Place the AA-MUX adapter on the hard disk tray and attach the four screws as shown. 2.
Accusys A16R/A16U-IS 3. Slide the hard disk towards the AA-MUX adapter and connect the power and data connectors. 4. Attach the screws to secure the hard disk. Note Please run DST (disk self test) function to verify the status of each disk before starting to configure the disk array, refer to the Software User Manual for detailed procedures.
Accusys A16R/A16U-IS Step 3. RAID System Connections Connecting RAID System to the Host There were 4 iSCSI channel interfaces on each controller. Each channel interface can be connected using standard Gat5/6 Ethernet cables. You can configure your RAID system for Direct Storage (DAS) by directly connecting to a host server or through an inexpensive gigabit Ethernet switch to build a Storage Area Network (IP-SAN). To connect the Ethernet cable: 1. Insert the cable to the CH port. 2.
Accusys A16R/A16U-IS 2. Connect the other end to the CH1 port of SAS JBOD enclosure. 3. After connecting the SAS connector, turn the power of the JBOD first, and then turn the power of the RAID system. 4. Power/Fan/Temp/HDD LED on JBOD lights up green and IO1&2 LED flashes when the connections are set up properly. Connecting the Power Once all of the components have been installed into the RAID system, and the management interfaces have been connected, the RAID system can now be powered on. Power on: 1.

Accusys A16R/A16U-IS Troubleshooting General Guidelines When you encounter issues, the most essential troubleshooting is to check the event log of your RAID system. In addition, you may need to check the system log of the operating system at your host computers. Because there are a wide variety of hardware and software combinations, use the following checklist for problem determination: • Check all cables to make sure they are connected properly.
Accusys A16R/A16U-IS • Disk bad block over threshold warning. • Disk group with degraded logical disk and no disk for rebuilding. • Disk group with faulty logical disks. • UPS failure or error. • Controller failure or removed. • Dual controllers fail to boot up because of configuration conflict. • Controller failback cannot proceed. Solutions See the table below for the solutions for the most common problems.
Accusys A16R/A16U-IS Multiple hard disks Could be system-level Use array recovery utility to the RAID are taken offline at a problem. For example, if the configurations. See the User’s mantime. hard disks in a JBOD system ual for more details. are offline unexpected, poor cabling in SAS or SAS expansion chain would also lead to unexpected hard disk offline. In addition, poor heat ventilation, unstable power supply, or hardware quality issues could also lead to offline of multiple hard disks.
Accusys A16R/A16U-IS The replacement controller stops bootup with LCD messages. If the conflict configuration can be resolved by overwriting the configuration of the replacement controller, the following LCD messages will be displayed and waiting for your confirmation by LCD ENT button: (H) CHK BC VERS: the two controllers have different boot code version. (I) CHK FW VERS: the two controllers have different firmware code version. (J) CHK BBM OPT: the two controllers have different BBM option.
