Drive Maintenance
RBL The drive is being rebuilt. A physical hard drive can
enter the RBL state if:
Ÿ
A good working drive replaces a defunct (DDD) drive
that is part of the critical logical drive. At the end of
a successful rebuild, the state of the physical drive
becomes online (ONL), and the state of the
corresponding logical drives changes to OKY.
Ÿ
An online drive that is part of a logical drive becomes
defunct (DDD) and an HSP or SHS drive with the
same or greater capacity is available. The state of the
hot-spare drive becomes RBL during the rebuild.
When the rebuild completes successfully, the state
changes to ONL; the former hot-spare drive is now
part of the logical drive.
Ÿ
A Ready (RDY) or Standby (SBY) drive replaces a
defunct (DDD) drive that is part of the critical logical
drives. The state of the RDY or SBY drive becomes
RBL during the rebuild. At the end of a successful
rebuild, the state of the drive becomes online (ONL);
the drive is now part of the logical drive.
For more information on rebuilding a drive, see
“Rebuilding a Logical Drive” on page 109.
RDY The 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. Devices such as tape drives and CD-ROM drives
are considered to be in a Standby state.
SHS A standby hot-spare is a hot spare drive that has been
spun down. 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 Rebuild process.
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.
