method

 

 

 

 

 

 

 

 

 

 

 

12

1)

Set the "Number of Retries" value in the MODE SELECT parameters at the "Default"

 

 

 

value.

 

 

 

2)

Reissue the original command (Retry). (Note)

 

 

3)

If the error is not recovered from after the first retry, issue the REZERO UNIT command.

 

 

4)

Reissue the original command (Retry). (Note)

 

 

5)

If the error is not recovered from, perform one of the following.

 

 

 

When the sense key is "HARDWARE ERROR [=4]," perform recovery method 1.

 

 

 

When the sense key is "MEDIUM ERROR [=3]," implement alternate block

 

 

 

allocation processing (shown in Section 6.4).

 

 

Note When the original command is the REASSIGN BLOCKS command, it may be

 

 

 

necessary to reconfigure the defect list. For details, see the description of the

 

 

 

REASSIGN BLOCKS command (Section 3.3.2).

 

 

 

 

 

13

1)

Generate the RESET condition or issue a BUS DEVICE RESET message for the IDD

 

 

 

that reported this error.

 

 

2)

After waiting 2 seconds or longer, reissue the original command (Retry), and if the

 

 

 

spindle motor's start mode is set on "Start by Command," issue the START instruction

 

 

 

by the START/STOP UNIT command ("Immed" = 0) before retrying.

 

 

3)

If the retry procedure (() does not terminate normally, perform recovery method 1.

 

 

 

 

 

14

1)

The MODE SELECT parameter is initialized at the "Save" value (if the "Save" value

 

 

 

does not exist, the "Default" value), so when it is necessary to set the inherent

 

 

 

parameter, issued the MODE SELECT command.

 

 

2)

Reissue the original command (Retry).

 

 

 

 

 

15

1)

When not linked from the SET LIMITS command, the cause of this error occurring is

 

 

 

that write operations at the setting terminal are prohibited, so cancel release that and

 

 

 

issue the original command. If it is impossible to release the write protected switch at

 

 

 

the system, perform recovery method 2.

 

 

2)

When linked from the SET LIMITS command, perform recovery method 2.

 

 

 

 

 

16

1)

Issue the LOG SENSE command and read the "Current" values in the LOG SELECT

 

 

 

parameters.

 

 

 

2)

If the parameters' values are appropriate, reissue the original command.

 

 

Note This error could also be caused by a UNIT ATTENTION condition being generated,

 

 

 

caused by a programming error of another INIT, so when the value in the parameter

 

 

 

read in ( is illegal, recovery method 2 should be performed, or the operations of the

 

 

 

other INITs should be confirmed.

 

 

 

 

17

If the PRIORITY RESERVE command issued by another INIT is proper in the system, performthe

 

 

necessary recovery processing in the system. If not, perform recovery method 2.
