SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

2. Issue a command specifying the previous configuration. The storage subsystem manager
then returns the configuration to its original setting.
For example, if you tried to add a mirror disk drive to a disk named $DATA, issue this SCF
command.
DELETE DISK $DATA-M
If you tried to move a mirror disk drive from location (2,1,5) to location (2,1,17) for a disk
named $DATA, issue these SCF commands:
DELETE DISK $DATA-M
ALTER DISK $DATA, MIRRORLOCATION (2,1,5)
01061
STORAGE E01061 Configuration changed, but subsystem-name returned error: errnum, error detail: error-detail.
subsystem-name
is the name of the subsystem returning the error message.
errornum
is a number identifying the error.
error-detail
is text that provides more information about the cause of the error.
Cause
An error occurred when you changed the disk configuration.
Effect
The configuration change took place. However, subsystem-name encountered an error
condition indicated by the value in errnum. The error-detail text species the processor
that the error condition affected.
Recovery
To determine whether or not to retry the command, refer to the errnum and error-detail
fields.
For example, if the error-detail text indicates a configuration status of “invalid in
processor n,” the change you made caused the configuration information in processor n to
become invalid. Such a situation might cause the loss of fault tolerance. For instance, the backup
disk might have lost its access to the mirror disk drive.
Depending on the error condition indicated by errnum and error-detail, perform either
of these two actions:
• Reissue the command that specified the new configuration. The storage subsystem manager
($ZZSTO) then retries the configuration change,
For example, if you previously tried to add a mirror disk drive in location (2,1,5) to a disk
volume named $DATA, issue this SCF command:
ALTER DISK $DATA, MIRRORLOCATION (2,2,5).
• Issue a command specifying the previous configuration. The storage subsystem manager
then returns the configuration to its original setting.
For example, if you tried to add a mirror disk drive to a disk named $DATA, issue this SCF
command:
DELETE DISK $DATA-M
01062
STORAGE W01062 The checksum has been corrected, but the disk data may not be valid.
Cause
CONTROL DISK, CHECKSUM was not able to read a good copy of the disk data.
