v
Reinstall the power supply.
If these tasks do not solve the problem, contact your IBM technical-support
representative.
19. Complete any remaining Recovery Guru procedures, if needed.
20. Check the status of each component in the storage subsystem.
21. Are any amber LEDs lit on any of the components?
v
Yes : Click Recovery Guru in the Subsystem Management window toolbar
and complete the recovery procedure. If a problem is still indicated, contact
your IBM technical-support representative.
v No: Go to step 22.
22. Create, save, and print a new storage subsystem profile.
Replacing a battery
The RAID controller in the storage subsystem contains a rechargeable battery
backup unit that provides power to back up the cache memory onto flash drives in
the event of a power failure. Each battery unit contains a sealed, rechargeable
SMART lithium ion battery. The cache battery is the only replaceable battery in the
storage subsystem.
Use the following procedure if the DS Storage Manager software instructs you to
replace the battery because the current battery has failed. You can also use the DS
Storage Manager software to check the status of the battery. Because write-caching
is disabled when the battery fails, replace the failed battery as soon as possible to
minimize any performance impact due to the disabling of the write-caching function.
Attention: When you handle static-sensitive devices, take precautions to avoid
damage from static electricity. For details about handling static-sensitive devices,
see “Handling static-sensitive devices” on page 19.
To replace a battery unit, complete the following steps.
1. Use the DS Storage Manager software to print a storage subsystem profile.
2. Read the safety information that begins on page xiii and “Best practices
guidelines” on page 5.
3. Locate the RAID controller that contains the failed battery unit (see “Controller
LEDs” on page 75).
Attention: Before you remove a controller in a single-controller DS3500, shut
down the DS3500 to avoid data loss (see “Turning off the storage subsystem”
on page 81).
4. Remove the controller from the chassis.
