Half-height device bay numbering Installation guidelines Observe the following guidelines when installing the SB40c: • • • An SB40c supports one partner server blade, and a partner server blade supports one SB40c. Install hard drives in the SB40c before installing the SB40c in the enclosure. Be sure that the partner server blade is powered down before installing the SB40c. Onboard Administrator is used to configure the enclosure and the SB40c. To function with the SB40c, Onboard Administrator version 1.
• • • Install the coupler plate on the SB40c. • If the SB40c is installed in an even-numbered bay, install the partner server blade in the adjacent odd-numbered bay to the left. • When installing the SB40c with a full-height server blade, a half-height server blade can be installed in the empty bay above the SB40c. This server blade cannot be partnered with the SB40c. Install the SB40c in any device bay on the lower row of the enclosure (9 through 16).
3. Remove the enclosure connector cover. 4. Identify the partner server blade to be installed with the SB40c: o To install the SB40c with a half-height server blade, proceed with the next step. o To install the SB40c with a full-height server blade, install the coupler plate.
5. Prepare the storage blade for installation. 6.
o 7. 8. Partnered with a full-height server blade Install a server blade. See the documentation that ships with the server blade. Configure the SB40c ("Configuration tools" on page 18).
Hardware options installation In this section Hard drive options ................................................................................................................................. 16 Hard drive options The SB40c supports up to six SAS or SATA hard drives. Always populate hard drive bays starting with the lowest device number.
2. Prepare the hard drive. 3. Install the hard drive. 4. Install the SB40c in the enclosure ("Installing a storage blade" on page 12). Power up the partner server blade. See the server blade documentation. Determine the status of the hard drive from the SAS and SATA hard drive LED combinations (on page 7). Configure the SB40c ("Configuration tools" on page 18). 5. 6. 7. HP Smart Array P400 Controller An HP Smart Array P400 Controller is used to manage the hard drives in the SB40c.
Configuration and utilities In this section Configuration tools ................................................................................................................................. 18 Management tools.................................................................................................................................. 19 Diagnostic tools .....................................................................................................................................
For more information regarding the default configurations that ORCA uses, refer to the HP ROM-Based Setup Utility User Guide on the Documentation CD. Management tools HP Systems Insight Manager HP SIM is a web-based application that allows system administrators to accomplish normal administrative tasks from any remote location, using a web browser. HP SIM provides device management capabilities that consolidate and integrate management data from HP and third-party devices.
Keeping the system current Change control and proactive notification HP offers Change Control and Proactive Notification to notify customers 30 to 60 days in advance of upcoming hardware and software changes on HP commercial products. For more information, refer to the HP website (http://h18023.www1.hp.com/solutions/pcsolutions/pcn.html).
Troubleshooting In this section When the storage blade does not power up.............................................................................................. 21 Diagnostic questions ............................................................................................................................... 21 Recognizing hard drive failure.................................................................................................................
Answer Possible reasons Possible solutions • • Remove any unused server blades, SB40cs, or interconnect devices. • Verify that the enclosure has sufficient power supply capacity available to operate all installed devices. • Verify that the enclosure power settings will enable the SB40c to start. • Add power supplies to meet the power requirement. • Verify that a sufficient number of cooling fans are in the enclosure.
Compromised fault tolerance If more hard drives fail than the fault-tolerance method allows, fault tolerance is compromised, and the logical drive fails. In this case, all requests from the operating system are rejected with unrecoverable errors. You are likely to lose data, although it can sometimes be recovered. One example of a situation in which compromised fault tolerance may occur is when a drive in an array fails while another drive in the array is being rebuilt.
• Do not remove a second drive from an array until the first failed or missing drive has been replaced and the rebuild process is complete. (The rebuild is complete when the online LED on the front of the drive stops blinking.) These cases are the exceptions: o In RAID 6 configurations, any two drives in the array can be replaced simultaneously. o In RAID 1+0 configurations, any drives that are not mirrored to other removed or failed drives can be simultaneously replaced offline without data loss.
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, reboot the server. The system may temporarily become operational long enough to allow recovery of unsaved data. In any case, locate the faulty drive, replace it, and restore data from backup.
4. 5. to indicate a successful connection. The online LED flashes, indicating that the SB40c recognized the drive replacement and began the recovery process. If applicable, power up the partner server blade ("Power up" on page 9). The SB40c reconstructs the information on the new drive, based on information from the remaining physical drives in the logical drive. While reconstructing the data on hot-plug drives, the online LED flashes. When the drive rebuild is complete, the online LED is illuminated.
