Logical Drive States (ServeRAID)

Logical Drive States

see also > Physical Device States

The state of the logical drive is determined by the state of the physical drives. Replacing a defunct drive with a good drive changes the state of the logical drive from offline (OFL) to critical (CRT) or good (OKY). When a defunct drive is replaced in a critical logical drive, the data is rebuilt in the replaced drive, before the state of the logical drive changes to OKY.

Status	Meaning

OKY	The drive is in a good functional state.

FRE	The drive is not defined.

OFL	The logical drive is offline and not accessible.
	This state occurs if one or more physical drives in a
	non-redundant logical drive (RAID level 0) is defunct.
	This state also occurs when two or more physical drives
	in a redundant logical drive (RAID levels 1 and 5) are
	defunct.

CRT	A logical drive that is defined as RAID level 1 or 5
	contains a defunct physical drive. A critical (CRT)
	logical drive is accessible despite a physical drive failure.

SYS	Reserved state used by the ServeRAID adapter.

LDM	The logical drive is undergoing a RAID level change.
	This state is only available in the remote system of the
	Administration and Monitoring program.

Note: If the logical drive is critical (CRT), you must rebuild the defunct drive.
