Description
Indicates the number of hard drives in the array.
Indicates the model, serial number, size, and
operational status of a hard drive related to the
port. If a hard drive is not present or cannot be
accessed, this output does not appear for that port.
Table 24-2 lists how hard drive bays map to the
port numbers.
A MARS RAID 10 configuration comprises
multiple RAID 1 subunits, each RAID 1 subunit
configured with two drives. The MARS 100 and
100e appliances have subunits numbered 0,1, and
2. MARS 200 appliances and Global Controllers
have subunits 0,1,2, and 3.
The two drives in each RAID 1 subunits have
unique physical port numbers.
The RAID 1 subunit status values are as follows:
OK—The subunit is in good order and
•
operating at optimal efficiency.
Rebuilding—The subunit is being rebuilt,
•
efficiency is not yet optimal.
Degraded—At least one physical disk in the
•
array cannot be accessed.
The rebuild processes can take between 90
minutes and two hours to complete, depending on
the amount of data on the disk. Subunits are
rebuilt one subunit at a time. The percentage
complete indicator tells you which subunit is
currently being rebuilt.
The Physical Port number appears as N/A when
the associated drive bay is empty.
Individual drive status is shown in the CBOD:
field. CDBOD status can be OK or DEGRADED.
