(2)Checking at abnormal end

a)When sense data can be obtained with the REQUEST SENSE command, analyze the sense data and retry recovery for a recoverable error. Refer to Chapter 4 of SCSI Logical Interface Specifications for further details.

b)Check the following items for the SCSI cable connection:

∙All connectors including other SCSI devices are connected correctly.

∙The terminating resistor is mounted on both ends of the cable.

∙Power is connected to the terminating resistor.

c)Check the setting of the terminals. Note that the checking procedure of SCSI connection differs depending on the setting of the motor start mode and UNIT ATTENTION report mode.

5.6.3Formatting

Since the disk drive is formatted with a specific (default) data format for each model (part number) when shipped from the factory, the disk need not be formatted (initialized) when it is installed in the system.

However, when the system needs data attributes different from the default format, all sides of the disk must be formatted (initialized) according to the procedures below.

The user can change the following data attributes at initialization:

∙Logical data block length

∙Number of logical data blocks or number of cylinders in the user space

∙Alternate spare area size

This section outlines the formatting at installation. Refer to Chapters 3 and 5 of SCSI Logical Interface Specifications for further details.

(1)MODE SELECT/MODE SELECT EXTENDED command

Specify the format attributes on the disk with the MODE SELECT or MODE SELECT EXTENDED command. The parameters are as follows.

a.Block descriptor

Specify the size (byte length) of the logical data block in the "data block length" field. To explicitly specify the number of logical data blocks, specify the number in the "number of data blocks" field. Otherwise, specify 0 in "number of data blocks" field. In this case, the number of logical data blocks after initialization is determined by the value specified in the format parameter (page code = 3) and drive parameter (page code = 4).

Its SCSI interface allows for multiple device connections, making it ideal for enterprise-level applications where performance is critical.

The MAE3091LC, on the other hand, also features a 10,000 RPM spindle speed but caters to a slightly lower capacity of 9.1 GB. Its Ultra SCSI interface ensures swift data throughput, making it suitable for data-intensive applications. The drive’s robust construction is designed to withstand the rigors of continuous operation, offering an MTBF (Mean Time Between Failures) rating that speaks to its reliability and endurance in demanding environments.

Moving on to the MAF3364LP, this model offers similar capacity to the MAF3364LC but operates at a lower power consumption rating, making it an eco-friendly choice for users who are conscious of energy usage. It retains the same high-speed performance capabilities, thanks to its efficient design and technology integrations.

The MAG3182LC is known for its high-capacity support and performance balance, with 18.2 GB of storage and a spindle speed of 10,000 RPM. It boasts enhanced data integrity features and advanced error correction technologies that allow for high data accuracy and reliability, ensuring that enterprises can depend on their stored information.

Lastly, the MAE3182LC offers a mix of performance and capacity, with its 18.2 GB storage. Utilizing a SCSI interface and maintaining a robust build, this drive is particularly suited for server environments that demand long continuous running times without compromising reliability.

In summary, these Fujitsu drives encompass advanced technologies, robust designs, and high-speed performance, catering to various needs from enterprise storage to high-demand applications. Their characteristics ensure that users receive not only adequate capacity but also reliability and efficiency, solidifying Fujitsu's reputation in the storage solutions market.
