5.4Checking Operation after Installation and Preparing the HDD for Use

(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 5 “Sense Data and Error Recovery Method” of the Fibre Channel Interface Specifications for further details.

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

5.4.3Formatting

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 recording surface 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 in the user space

Alternate spare area size

This section outlines the formatting at installation. Refer to Subsection 4.1.4 “MODE SELECT (15)”, 4.1.5 “MODE SELECT EXTENDED (55)” of the Fibre Channel 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).

b.Format parameter (page code = 3)

Specify the number of spare sectors for each cell in the "alternate sectors/zone" field. It is recommended not to specify values smaller than the HDD default value in this field.
