drive becomes online (ONL), and the state of the
corresponding logical drives changes to OKY.
The HSP or SHS drive is added to the array and the
state changes from HSP or SHS to RBL. At the same
time, the DDD drive is removed from the array and
its state changes to DHS from DDD. The ServeRAID
adapter will then automatically reconstruct data in the
RBL drive. The state of the corresponding logical
drive remains in CRT (if RAID level 1 or 5) or OFL (if
RAID level 0) during the rebuild process. When the
rebuild completes successfully, the device state
changes from RBL to ONL and the logical drive state
changes from CRT to OKY.
A Ready (RDY) or Standby (SBY) drive replaces a
defunct (DDD) drive that is part of the critical (CRT)
logical drive. The state of the RDY or SBY drive
becomes RBL. When the rebuild completes
successfully, the state changes to ONL. The DDD
drive is removed from the logical drive and becomes
DHS.
For more information on rebuilding a drive, refer to
“Important Information for Rebuilding a Logical Drive”
on page 60.
RDY
A ready drive is recognized by the adapter and is
available for definition. A RDY drive becomes EMP when
the drive is physically removed from the bay.
SBY
A standby drive is a hard disk drive that has been spun
down by the adapter. Devices such as tape drives and
CD-ROM drives are also considered to be in a Standby
state.
SHS
A standby hot-spare is a hot-spare drive that has been
spun down by the adapter. If a drive becomes defunct
and no suitable hot-spare drive is available, a standby
hot-spare of the appropriate size spins up, and enters the
RBL state. You must have at least four hard disk drives,
if you want a standby hot-spare and RAID level 5.
TAP
A tape drive is installed.
