Equipment symbols The following symbols may be located on equipment in areas where hazardous conditions may exist. WARNING! Any enclosed surface or area of the equipment marked with these symbols indicates the presence of electrical shock hazards. Enclosed area contains no operator serviceable parts. To reduce the risk of injury from electrical shock hazards, do not open this enclosure.
Page 66: Weight Warning
Weight warning WARNING! The device can be very heavy. To reduce the risk of personal injury or damage to equipment: • Remove all hot-pluggable power supplies and modules to reduce the overall weight of the device before lifting. • Observe local health and safety requirements and guidelines for manual material handling. •...
Page 67: Device Warnings And Precautions
WARNING! Verify that the AC power supply branch circuit that provides power to the rack is not overloaded. Overloading AC power to the rack power supply circuit increases the risk of personal injury, ﬁre, or damage to the equipment. The total rack load should not exceed 80 percent of the branch circuit rating. Consult the electrical authority having jurisdiction over your facility wiring and installation requirements.
Page 68 CAUTION: To properly ventilate the system, you must provide at least 7.6 centimeters (3.0 inches) of clearance at the front and back of the device. CAUTION: When removing or replacing a failed component, allow 30 seconds to pass before inserting a replacement component.
Page 69: Determining Whether A Component Is Hot-Pluggable
Determining whether a component is hot-pluggable Before removing any serviceable part, determine whether the part is hot-pluggable or non-hot-pluggable. • If the component is hot-pluggable, a power shutdown of the device is not required for replacement of the part. • If the component is not hot-pluggable, the device must be powered down.
Page 70: Connecting Power To The Msa
Connecting power to the MSA HP strongly recommends using the power cord shipped with the MSA. If using a different power cord, your power cord should be approved for use in your country. The power cord must be rated for the product and for the voltage and current marked on the electrical ratings label of the product.
Page 71: Applying Power To The Msa
Applying power to the MSA Before applying power to the MSA, all components of the storage system must be installed and connected to the supported interconnect options. Hard drives should be installed in the enclosures so that they can be identiﬁed and conﬁgured at power up. The MSA and the other network components must be powered on in the following sequence: Verify that the following devices are powered on and in a ready state: •...
Page 72: Removing Power From The Msa
Removing power from the MSA CAUTION: System power to the MSA does not shut off completely with the power switch. The two positions of the Standby front panel power switch should be considered as , rather than . The standby position removes power from most of the electronics and the hard drives, but portions of the power supply and some internal circuitry remain active.

Page 93: Enclosure And Hard Drive Migrations
7 Enclosure and hard drive migrations This section describes the following: • Adding a new storage enclosure • Migrating existing enclosures • Moving hard drives or arrays NOTE: For the most up-to-date information on supported enclosures, see the MSA website. Adding a new storage enclosure New storage enclosures with unconﬁgured hard drives are hot-pluggable.
Page 94: Moving Hard Drives Or Arrays
Attach SCSI cables to the MSA expansion SCSI connectors. Attach the SCSI cables to the expansion storage enclosures. Attach the power cords to the power supplies at the rear of the enclosures. Power on each enclosure and wait for it to complete its startup routine. Power on the MSA array controller system using the power button on the front of the system.
Page 95: Capacity Expansion And Extension
8 Capacity expansion and extension Array expansion is the addition of physical hard drives to an array that has already been conﬁgured. The capacity of these added physical hard drives may then be added to an existing LUN on the array or conﬁgured into a new LUN.
Page 96 Capacity expansion and extension...
Page 97: Hard Drive Failures And Faulted Luns
9 Hard drive failures and faulted LUNs The purpose of fault-tolerant array conﬁgurations is to protect against data loss due to hard drive failure. Each RAID conﬁguration has inherent limitations on the number of hard drive failures that it can tolerate. If the fault-tolerance level of a particular LUN or array conﬁguration is exceeded, the array will be locked from any further I/O.
Page 98: Compromised Fault Tolerance
• RAID 6 conﬁgurations can tolerate simultaneous failure of two hard drives in the array. Compromised fault tolerance Each RAID conﬁguration has inherent limitations on the number of physical hard drive failures that it can tolerate. If more hard drives fail than the fault-tolerance method allows, fault tolerance is compromised. When the MSA determines that the fault tolerance of a LUN is compromised, the LUN is taken ofﬂine and subsequent I/O requests are rejected.
Page 99: Best Practices When Replacing Hard Drives
b. Make copies of important data, if possible. Replace any failed hard drives and allow the Automatic Data Recovery (ADR) process to rebuild the data onto replacement drives. d. After failed hard drives have been replaced, fault tolerance may again be compromised. If so, power cycle the system, and if the #02 or #04 ENABLE VOLUME LCD message is displayed, press the right push button to re-enable the LUNs.
Page 100: Automatic Data Recovery (Rebuild)
• When RAID 6 (ADG) is used, two drives can fail simultaneously (and be replaced simultaneously) without data loss. • If the ofﬂine drive is a spare, the degraded drive can be replaced. • Do not remove a failed second hard drive from an array until the ﬁrst failed or missing hard drive has been replaced and the rebuild process is complete.
Page 101: Failure Of Another Drive During Rebuild
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 and the storage system. The system may temporarily become operational long enough to allow recovery of unsaved data.
