Replace Brick Disk Drives

Pillar Data Systems Confidential
Note: When Guided Maintenance beacons the disk drive to
identify it, Guided Maintenance:
• Turns off the top and bottom LEDs.
• Blinks the middle LED.
Important!
Use Guided Maintenance to coordinate the
replacement of the target disk drive. The system may need to
copy data from the target disk drive to the spare disk drive.
This process may cause some performance degradation
along user data paths while the data is copied. Some
performance degradation may also occur when the data is
copied back after the disk drive is replaced.
