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. |
