NONCRITICAL

Condition

A drive enclosure EMU condition report that occurs when one or more elements

inside the enclosure have failed or are operating outside of their speciﬁcations.

The failure does not a ffect continued normal o p eration of the enclosure. All

devices in the enclosure continue to operate according to their speciﬁcations.

The ability of the devices to operate correctly may be reduced if additional

failures occur. UN RECOVERABLE and CRITICAL errors have precedence over

this condition. This condition has precedence over INFORMATION c ondition.

Early correction ca n prevent the loss of data.

node port A device port that can operate on the arbitrated loop topology.

non-OFC (Open

Fibre Control)

A laser transceiver whose lower-intensity output does not require special open

Fibre Channel mechanisms for eye protection. The E nterprise storage system

transceivers are non-OFC compatible.

NSC Network Storage Controller. The HSV Controllers used by the Enterprise storage

system.

NVRAM Nonvolatile Random Access Memory. Memory whose contents are not lost when

the use of UPS ba tteries or implementation technology such as ﬂash memory.

NVRAM is commonly used to store important conﬁguration parameters.

occupancy alarm

level

A percentage of the total disk group capacity in blocks. When the number of

blocks in the disk group that contain user data reaches this level, an event code

is generated. The a larm level is speciﬁed by the user.

OCP Operator Control Panel. The elem ent that displays the controller’s status using

indicators and an LCD. Information selection and data entry is controlled by

the OCP push buttons.

online/nearonline An online drive is a normal, high-perfomance drive, while a near-online drive

is a lower-per formance drive.

age Management

Server

A centralized, appliance-based monitoring and management interface that

supports multiple applications, operating systems, hardware platforms, storage

systems, tape libraries and SAN-related interconnect devices. It is included and

resides on the SANWorks Management Server, a single aggregation point

for data management.

param That portion of the HSV controller termination code display that deﬁnes:

• The 2-character parameter identiﬁer that is a decimal number in the 0

through 30 range.

• The 8 -character parameter code that is a hexadecimal number.
