Preface III
The message code.
z
The message postfix, such as E for errors and W for warnings.
rrrrr
The request sequence number that identifies the AutoSwap command request on a particular host. This value is
incremented each time a new command request is made. All messages associated with the same request on the same
host are prefixed by the same request sequence number.
>host
The SMF ID of the host from which the message was routed.
ppppp
A process ID (PID) that is a unique incrementing value for each swap validation or swap process (that is, device pair) for
the same swap group definition. This value always follows the request sequence number or host to uniquely identify the
messages relating to the same device pair swap within the same swap group.
When a cross-system validation or swap is performed, the same PID is used on all hosts. The PID is set by the AutoSwap
owner host when the swap group is created and remain the same for the life of the swap group.
Verbosity
Some messages are only produced when the verbosity level (set with the SET VERBOSE command of AutoSwap) is greater
than or equal to the verbosity level of the message. Error messages and most warning messages are always produced no
matter what verbosity level is set. Verbosity levels are as follows:
0—Messages that are basic summaries of a condition or state. Such messages are initially interesting, but describe a
condition that occurs regularly, and thus generates a large number of messages.
1—Messages relating to the initiation and termination of a swap or device validation
2—Messages relating to the initiation of a swap or validation phase
3—Interphase informational messages
4—Non-SRDF swap processing informational messages
10—Swap request initiation or termination messages
Variables
The FROM and TO devices can be displayed as sccuu or, when the CUU cannot be located, as symms,symdv#, with 2
leading digits of the device number suppressed when zero.
In sccuu, if the set number s is not visible, the set is automatically assumed as the active set number.
seq# is the request sequence number ID. It is assigned when a command request is accepted for processing. All messages
related to the command request have the assigned sequence number in message text.
The host-id value is interpreted as follows: ttccxxxxxxxxaaaa, where:
tt is the operating system type. Valid values include:
01 indicates z/OS.
‘--’ indicates that SCF is not active or the host type is unknown. This is only displayed where path groups are
defined to a device and an active SCF CSC cannot be located.
cc is the CPU address of LPAR identifier (when in LPAR mode).
xxxxxxxx is the CPU identifier and machine type (model number).
aaaa is the address space identifier (ASID) of SCF on that host. ‘----’ indicates that SCF is not active. This is only
displayed where path groups are defined to a device and an active SCF CSC session cannot be located.
