5. Hot

Spare

Mode

The operation after replacement of the defected disk by the hot spare repair can be
specified by using the management software (NEC Storage Manager).

ON (Level-b0):

Restores data after replacement of defected disk (default).

OFF (Level-A):

Does not restore data after replacement of defected disk. The new disk is changed to
the spare disk.

Contact the service engineer with expert knowledge in your sales agent for the operation.

6.

1-BBU Cache Enable Mode

If only a single BBU is installed, the write cache operation mode can be set by using the
management software (NEC Storage Manager).
However, immediate replacement by maintenance personnel is required at the occurrence
of a fault for a single BBU because redundancy of data may be lost.    Further, be careful
because retention time of data becomes half on this occasion.

OFF:  Provides operation in the write cache disable mode in the 1-BBU status.
ON:  Provides operation in the write cache enable mode even in the 1-BBU status.

(default)

The 1-BBU status means that only a single BBU is installed in the system or the available
number of installed BBUs is 1 due to occurrence of a fault.

To set the mode, contact the service engineer with expert knowledge in your sales agent.

7.

1-Controller Cache Enable Mode

If only a single controller is installed, the write cache operation mode can be set by using
the management software (NEC Storage Manager).
However, it is recommended to set the mode to OFF because data may be lost at the
occurrence of a fault for a single controller.

OFF: Provides the operation in the write cache disable mode for the 1-controller status.

(default)

ON: Provides the operation in the write cache enable mode even for the 1-controller

status.

The 1-controller status means that only a single controller is installed in the system or the
available number of installed controllers is 1 due to occurrence of a fault.

To set the mode, contact the service engineer with expert knowledge in your sales agent.
