The paths to the primary volume (P-VOL) in an HAM environment have
recovered from an error, but I/O to the P-VOL is suppressed. If an error
occurs in all the paths to a secondary volume (S-VOL), the status of the
P-VOL paths will be automatically changed to the Online status. To
change the status to the Online(D) status, specify the -dfha parameter
for the HDLM command's online operation.
#
The status changes to this status when using HAM (High Availability
Manager).
The Offline Path Status
The offline path statuses are as follows:
•
Offline(C)
The status in which I/O cannot be issued because the offline operation
was executed. For details on the offline operation, see
The (C) indicates the command attribute, which indicates that the path
was placed offline by using the command.
•
Offline(E)
The status indicating that an I/O could not be issued on a given path,
because an error occurred on the path.
The (E) means error.
