Recovery
method
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.
18
1)
Issue the MODE SENSE or MODE SENSE EXTENDED command and confirm
the values of the disk media data format related parameters (Block descriptor, Page
3: Format parameters, Page 4: Drive parameters).
2)
If the parameter values are correct, issue the FORMAT UNIT command and
initialize the entire disk media surface. (Note)
3)
If the parameter values are not correct, issue a MODE SELECT or MODE SELECT
EXTENDED command and reset the necessary parameters, then reinitialize the
entire disk media surface by the FORMAT UNIT command. (Note)
Note In a system where multiple INITs are connected together, an error may have been
reported due to a MODE SELECT or MODE SELECT EXTENDED command, or a
FORMAT UNIT command issued by another INIT, so before executing this
recovery method, it is necessary to confirm the operations of the other INITs.
19
Initialize the entire disk media surface. It is desirable at this time to increase the number
of spare sectors as much as possible. If this error occurs repeatedly, it is necessary to
perform alternate block allocation processing through the system (shown in Chapter 5) or
reconfirm the use conditions of the disk drive, such as the installation environment.
20
1)
Reissue the original command (Retry).
2)
If it doesn't recover after 10 retries, perform recovery method 13.
21
1)
Issue the MODE SENSE or MODE SENSE EXTENDED command and read the
"Current" values in the MODE 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 values in the
parameters read in ( are illegal, recovery method 2 should be performed, or the
operations of the other INITs should be confirmed.
22
Reissue the original command (Retry).
23
1)
If it is necessary to reestablish rotational synchronization, issue the MODE
SELECT or MODE SELECT EXTENDED command (specify by Page 4, byte 17).
2)
Reissue the original command (Retry).
