Removal and replacement procedures
Warning and caution messages WARNING! To reduce the risk of personal injury or damage to equipment, heed all warnings and cautions throughout the installation instructions. WARNING! To reduce the risk of personal injury or damage to the equipment, be sure that: • The leveling jacks are extended to the floor. • The full weight of the rack rests on the leveling jacks. • The racks are coupled together in multiple-rack installations. • Only one component is extended at a time.
CAUTION: Always be sure that equipment is properly grounded and that you follow proper grounding procedures before beginning any installation procedure. Improper grounding can result in ESD damage to electronic components. For more information, see “Preventing electrostatic discharge” (page 7) CAUTION: When performing non-hot-plug operations, you must power down the server blade and/or the system. Use caution when performing other operations, such as hot-plug installations or troubleshooting.
Power cords To reduce the risk of electric shock or damage to the equipment: • Use an approved power cord. If you have questions about the type of power cord to use, contact your HP authorized service provider. • If you have not been provided with a power cord for your product or for any AC-powered option intended for your product, purchase a power cord that is approved for use in your country.
Powering on After disk enclosures are physically installed and cabled, power up all devices and verify that they are operating properly. Before powering on Observe the following best practices before powering on the enclosure for the first time: • Complete the server, controller, or controller enclosure installation. For more information, see the server, controller, or controller enclosure user documents. • Install the disk enclosures.
Verifying the operating status of the disk enclosures To verify that the disk enclosures and disk drives are operating properly, view the enclosure and disk drive LEDs and compare them with the patterns described in the following table. If LED patterns are not as expected, check cable connections between the devices, check the availability of your power source, review the installation procedures, and remove and reinsert the module. Front panel LEDs Indicator Startup condition 1. HDD N/A 2.
I/O module LEDs Indicator Startup condition Operating condition Fault conditions 1. Port Link Blinking or solid green Off 2.

Solid green The drive is a member of one or more logical drives.
Disk drive guidelines CAUTION: • Follow industry-standard practices when handling disk drives. Internal storage media can be damaged when drives are shaken, dropped, or roughly placed on a work surface. • When installing a disk drive, press firmly to make sure the drive is fully seated in the drive bay and then close the latch handle. • When removing a disk drive, press the release button and pull the drive only slightly out of the enclosure.
• 2. If you are replacing a disk drive, refer to “Removing a drive” (page 16) Unlatch and swing out the latch handle on the drive. Then, slide the drive into the bay (1), pressing firmly on the drive to seat it. Close the latch handle (2), pressing firmly until it locks in place. IMPORTANT: When a drive is inserted in an operational enclosure, the drive LEDs flash to indicate that the drive is seated properly and receiving power. 3. 4.

NOTE: Depending on whether the drive cage is for LFF or SFF drives, the screws are in slightly different locations. 12. Slide the drive cage toward the front of the enclosure and lift free of the enclosure. 13. Remove the two T-15 screws attaching the back plane to the drive cage. 14. Slide the back plane toward the top of the drive cage and lift the back plane off the drive cage. 15. Place the new back plane on the drive cage and slide toward the bottom of the drive cage on to the retaining hooks. 16.
Installing the rail kit The disk enclosure can be installed into most standard server racks. To verify that your rack is supported for use with the disk enclosure, see the QuickSpecs for the disk enclosure at the HP website: http://www.hp.com. CAUTION: Install disk drives in the enclosures only after mounting the enclosures in the rack. • A disk enclosure populated with disk drives is too heavy to lift safely by a single person.
Procedures 1. Position left and right rack rails at the desired 'U' position in the rack, adjusting the rails to fit the rack, as needed. Front and Rear bottom edge of rails must align with the bottom of EIA boundary in the lowermost 'U' NOTE: Rails are marked L and R with an arrow indicating the direction in which the rail should be installed. 2. 3. Use guide pins to align the shelf mount kit to the RETMA column holes.
8. Attach rear hold down brackets by sliding the tab with the arrow pointed forward (1) into the corresponding slot on the left and right side of the rear of the chassis. Use the black headed thumb screw to secure tightly to the rail (2).
3 Troubleshooting If the enclosure does not initialize IMPORTANT: After a power failure, the system automatically returns to the On state when A/C power is restored, except in the following cases: • If both power supplies are damaged. • If there is a single power supply in the system, and it is damaged. 1. 2. 3. Ensure that power has been applied to the enclosure. Verify that the power LED is green. Verify that the power source is working: a.

Recognizing disk drive failure In an HP enclosure, a steadily glowing fault LED indicates that a disk drive has failed. Other indications of failed disk drives are as follows: • ACU represents failed drives with a distinctive icon. • HP SIM can detect failed drives remotely across a network. (For more information about HP SIM, see the documentation on the Management CD.) • ADU lists all failed drives.
To minimize the likelihood of fatal system errors, take these precautions when removing failed drives: • Do not remove a degraded drive if any other drive in the array is offline (the online LED is off). In this situation, no other drive in the array can be removed without data loss. • Exceptions: • ◦ When RAID1+0 is used, drives are mirrored in pairs.
When automatic data recovery has finished, the online LED of the replacement drive stops blinking and begins to glow steadily. Failure of another drive during rebuild If a non-correctable read error occurs on another physical drive in the array during the rebuild process, the Online LED of the replacement drive stops blinking and the rebuild abnormally terminates. If this situation occurs, restart the server. The system might temporarily become operational long enough to allow recovery of unsaved data.
