PS6210 Hardware Owner's Manual
If a Spare Drive Is Not Available
If a spare drive is not available, the RAID set will become degraded and performance might be
impaired. However, a RAID 6 set can survive two simultaneous drive failures.
If a spare drive is not available and the failed drive is in a RAID set that is already degraded, data
might be lost and must be recovered from a backup.
Drive Handling Requirements
Handle drives as follows:
•
Protect drives from electrostatic discharge. Wear an electrostatic wrist strap when handling a
drive. See
Protecting Hardware on page
•
Store drives properly. Store replacement drives in the packaging in which they were shipped. Do
not stack drives or place anything on top of a drive.
•
Handle drives carefully. Hold a drive only by the plastic part of the carrier or the handle. Do not
drop, jolt, or force a drive into a slot.
•
Warm replacement drives to room temperature before installation. For example, let a drive sit
overnight before installing it in an array.
•
Do not remove a functioning drive (other than a spare) from an array. If the drive is not a spare, the
RAID set might become degraded. If you remove a spare, replace the drive as soon as possible.
•
Do not leave drive slots empty. Each drive slot in an array must contain a drive assembly or a blank
carrier. Operating an array with an empty slot will void your warranty and support contract.
•
Do not remove a drive from its carrier. This action will void your warranty and support contract.
•
Keep the shipping material. Return a failed drive to your array support provider in the packaging in
which the replacement drive was shipped. Shipping drives in unauthorized packaging might void
your warranty.
Drive Installation Guidelines and Restrictions
•
Replace a failed drive as soon as possible, to provide the highest availability.
•
Install only drives of the same type, speed, and spin rate in an array.
•
You can use drives of different capacities in the same array. However, the smallest drive in the
array will determine how much space can be used on each drive. For example, if the smallest drive
is 400GB, only 400GB of space will be available for use on each drive.
•
Make sure the drive is oriented in the correct position for the array model. See
Features and Indicators on page
•
Insert a drive fully in the chassis before pushing in the handle.
•
When correctly installed, a drive will be flush with the front of the array. If the drive is protruding
from the array, reinstall the drive.
•
After installation, make sure the drive power LED is green or flashing green. See
Failed Drives on page
•
A two-minute delay occurs between the time you insert a drive and the time the drive is
automatically configured into a RAID set. This time interval allows multiple drives to be
simultaneously configured in an array, which is more efficient than installing a single drive,
configuring it, and then repeating the process.
