TAP A tape drive is installed.
Logical drive states:
Descriptions of the logical drive
states, which appear in the Logical Drive list, are as
follows:
State Meaning
CRM A logical drive undergoing a logical-drive
migration (LDM) is in the critical state.
CRS The ServeRAID controller uses this reserved
state during a logical-drive migration (LDM).
CRT A RAID level 1 or 5 logical drive that contains
a defunct physical drive is in the critical state.
A critical (CRT) logical drive is accessible,
despite a physical drive failure.
FRE The drive is in a free (FRE) state. It is not
defined.
LDM The logical drive is undergoing a logical-drive
migration (LDM); that is, a change in RAID
levels, a change in logical drive size, or an
increase in free space.
OFL The logical drive is offline (OFL) and not
accessible. This state occurs if one or more
physical drives in a RAID level 0 logical drive
are defunct. This state also occurs when two
or more physical drives in a RAID level 1 or
RAID level 5 logical drive are defunct.
OKY The drive is okay (OKY). It is in a good,
functional state.
SYS The ServeRAID controller uses this reserved
state during logical-drive migration (LDM).
If the state of the logical drive is critical (CRT), you must
replace and rebuild the defunct drive. See “Understanding
the drive rebuild process” on page 131 for more
information.
