HP DL380z Gen8 Virtual Workstation - Manual (Page 54)

Removing a hot-plug SAS or SATA hard drive
CAUTION: For proper cooling, do not operate the server without the access panel, baffles,
expansion slot covers, or blanks installed. If the server supports hot-plug components, minimize the
amount of time the access panel is open.
1. Determine the status of the drive from the hot-plug SAS drive LED combinations ( Hot-plug drive
LED definitions on page 13 ).
2. Back up all server data on the drive.
3. Remove the drive.
Controller options
The server ships with an embedded Smart Array P420i controller. For more information about the
controller and its features, see the HP Smart Array Controllers for HP ProLiant Servers User Guide
on the HP website ( http://www.hp.com/support/SAC_UG_ProLiantServers_en ). To configure arrays,
see the Configuring Arrays on HP Smart Array Controllers Reference Guide on the HP website
( http://www.hp.com/support/CASAC_RG_en ).
Upgrade options exist for the integrated array controller. For a list of supported options, see the
QuickSpecs on the HP website ( http://www.hp.com/support ).
The server supports FBWC. FBWC consists of a cache module and a capacitor pack. The DDR
cache module buffers and stores data being written by the controller. When the system is powered
on, the capacitor pack charges fully in about 5 minutes. In the event of a system power failure, a fully
charged capacitor pack provides power for up to 80 seconds. During that interval, the controller
transfers the cached data from DDR memory to flash memory, where the data remains indefinitely or
until a controller retrieves the data.
CAUTION: The cache module connector does not use the industry-standard DDR3 mini-DIMMs. Do
not use the controller with cache modules designed for other controller models, because the
controller can malfunction and you can lose data. Also, do not transfer this cache module to an
unsupported controller model, because you can lose data.
CAUTION: To prevent a server malfunction or damage to the equipment, do not add or remove the
battery pack while an array capacity expansion, RAID level migration, or stripe size migration is in
progress.
CAUTION: After the server is powered down, wait 15 seconds and then check the amber LED
before unplugging the cable from the cache module. If the amber LED blinks after 15 seconds, do not
remove the cable from the cache module. The cache module is backing up data, and data is lost if the
cable is detached.
