Users Guide
The controller automatically performs the Transparent Learn Cycle (TLC) on the battery to calibrate and gauge its charge capacity once
every 90 days. The operation can be performed manually, if required.
NOTE: Virtual disks stay in Write Back mode, if enabled, during transparent learn cycle. When the TLC completes, the controller
sets the next TLC to +90 days.
Transparent Learn Cycle Completion Time
The time frame for completion of a learn cycle is a function of the battery charge capacity and the discharge and charge currents used.
Typical time completion for a transparent learn cycle is between 4-8 hours. If the learn cycle is interrupted mid cycle, it begins at a new
cycle.
Conditions for replacing the battery
The PERC battery is marked Failed when the state or health of the battery is declared bad. If battery is declared failed then the rmware
runs learn cycles in subsequent reboots until the battery is replaced. After replacing the battery, virtual disk transitions to Write Back mode.
Non-RAID disks support
By default, all the disks are in RAID capable uncongured state. The user can also convert the RAID capable disks to non-RAID disks using
either the BIOS conguration utility or the UEFI/HII RAID conguration utility.
Creating a non-raid disk
To create a non-RAID disk, perform the following steps in the BIOS Conguration Utility (<Ctrl> <R>):
1 In the Virtual Disk Mgmnt screen, use the arrow keys to highlight the PERC 9 adapter or Disk Group #.
2 Press <F2>.
The list of available action is displayed.
3 Click Convert to Non-RAID.
The Convert RAID Capable Disks to Non-RAID window is displayed.
4 Press the down-arrow key to highlight an available physical disk.
5 Press the spacebar to select the disk.
NOTE
: An X is displayed beside the selected physical disk(s).
6 Select OK.
