2 CLI Commands This chapter describes the functions of the commands available in the CLI for Business Continuity Manager. Copy Types and Targets for Which Commands Can Be Executed This section explains the copy types and targets for which commands can be executed. Each command has certain copy types and targets that it can execute. The copy types and targets for which commands can be executed are indicated below.
Table 95 List of Supported Functions (continued) Command 1 Function YKDROP Drops a REXX variable structure that has been loaded from a script by using the YKLOAD command and then expanded. YKENV Obtains a Business Continuity Manager environment variable and displays it in the TSO/E terminal. YKERCODE Displays storage system sense byte information (error codes) on the TSO/E terminal. YKEWAIT Monitors the copy pair status transition and waits for a certain specified status.
3 The YKWATCH command is a REXX script. 4 The YKWTOMSG command is a REXX function. Configuration Files That Must Be Loaded Before Command Execution Table 96 (page 181) and Table 97 (page 183) show the configuration files that must be loaded before each command is executed. Table 96 (page 181) shows the configuration files that must be loaded in an environment that does not contain a Non Gen'ed volume and where the following conditions exist: • The P-VOL is recognized by the host.

For details about the syntax symbols used in the explanations, see “Symbols Used in Syntax Explanations” (page 389) YKBLDCMD Command Applies to CMD.
APID(APID) ~ Specify the APID. MSG(stem-name-1) ~ Specify an optional prefix for the name of the message structure used to store the messages to be generated by this command. You must also include a trailing period character. The message structure is initialized when the CLI command with the same name as the MSG parameter is specified. NOTE: • Execute the YKBLDCMD command only once after turning on the storage system.
YKBLDPTH Command Applies to PTH. Format YKBLDPTH 1STEM(stem-name-1) 1MSG(stem-name-2) [ 1PSN(storage system-serial-number)[ [ 1SSN(storage system-serial-number)[ [ 1PTID(path-group-ID)] [ 1{FORWARD|REVERSE}] [ 1TYPE({CU|DKC})] 1PCU(cu-number)]] 1SCU(cu-number)]] Function This command is a TSO/E command called from REXX scripts.
and inter-DKC logical paths will be established such that the paths treat the storage system (that has the serial number specified by this parameter) as the secondary storage system. If neither this parameter nor any other parameters are specified, the command establishes all logical paths.
NOTE: • Before executing the command, create and load the path set definition file. • If a message that contains sense information for the storage system is output, see the list of error codes in the HP XP7 for Business Continuity Manager Messages and then eliminate the cause of the error.
Function This command is a TSO/E command called from REXX scripts. This command monitors for the following messages: • IEA494I message Copy status display message that is output to the MVS console • IOSHM0414I message HyperSwap completion message that is output to the MVS console • User-specified message User-specified message that indicates that a HyperSwap has been completed Parameters MSGID({IEA494|IOSHM0414I|user-specified-message-ID}) Specifies the message to be monitored.

Specify the value returned in the YKCONMSG OP(OPEN) command's completion message as the handle value. NOTE: • In some configurations such as when BC and CA share volumes or a 1 to n (n is greater than 1) configuration of BC, the status transitions of each copy pair might not be correctly monitored.
Format YKDELCMD { 1SN(storage system-serial-number)| 1SN(storage system-serial-number) 1CU(cu-number) 1DEVN(device-number) 1APID(apid)} 1MSG(stem-name-1) 1CCA(cca-number) 1APID(apid)| Function This command is a TSO/E command called from REXX scripts. The command deletes, from the storage system, the command device that was specified in the route list that was loaded before this command was executed.
NOTE: • For the YKDELCMD command, you need to input the storage system for the Primary site and Secondary site, according to the reverse of the site order defined in the route list. Be sure to perform input in the order of the secondary site and Primary site. • If you delete command devices for a storage system for which multiple command devices have been defined, processing continues even if an error occurs for one or more of the command devices.
Format YKDELETE 1STEM(stem-name-1) 1MSG(stem-name-2) [ 1DEVN(p-vol-device-number,s-vol-device-number)] [ 11SELECT({ALL|COND})] Function This command is a TSO/E command called from REXX scripts. This command dissolves a copy pair for the specified copy group and changes the volume status to the SIMPLEX status. When dissolving copy pairs in an EXCTG container, if all copy pairs are dissolved from a journal group, that journal group will be deleted from the EXCTG.
NOTE: • Do not execute the YKDELETE command during planned outage operation (when switching the P-VOL and S-VOL). To dissolve the copy pair, switch the P-VOL and S-VOL again, return the P-VOL to the primary site (restore normal operation), and then dissolve the copy pair. • When operating the copy groups of a copy pair that was deleted with the DEVN parameter, for the time that the copy pair is being synchronized, be sure to specify the SELECT(COND) parameter.
Table 102 YKDELETE Command Return Code List (continued) Return Code Meaning 48 Terminating due to invalid parameters. This return code appears, for example, when the copy pair corresponding to the device number specified with the DEVN parameter is not found. 128 The command terminated abnormally. The user does not have permission to execute this command. YKDELPTH Command Applies to PTH.
PCU(cu-number) ~ <2-digit hexadecimal number> If this parameter is specified, out of the logical paths within the path set stored in the path set structure specified for the STEM parameter, inter-CU logical paths will be deleted in all cases where the CU number of the MCU matches the value specified for this parameter. Inter-DKC logical paths are not affected by this parameter. If neither this parameter nor any other parameters are specified, the command establishes all nonshared inter-CU logical paths.
FORCE If this parameter is specified, of those logical paths that are identified in the path set stored in the path set structure specified by the STEM parameter, the command also deletes the paths that have the shared attribute (those with the value Y assigned to stem-name-specified-in-STEM-parameterPATH.n.Shared). If this parameter is not specified, the command does not delete logical paths that have the shared attribute.
Table 103 YKDELPTH Command Return Code List (continued) Return Code Meaning 32 • I/O errors were encountered. None or only some of the logical paths were deleted. • A change in an I/O configuration definition was detected. 36 • Processing was interrupted because a REXX variable with an invalid value was encountered. None or only some of the logical paths were deleted. • No path to be deleted was found. 40 An error occurred while a REXX variable was being read or written.
For either the GRP or the PTH parameter, specify the prefix of the copy group structure related to the REXX variable structures to be dropped. If you specify the GRP parameter, the REXX variable structures related to the copy group structures will be dropped.

This command displays the details of a specified error code on the TSO/E terminal. The command displays the following information: • Error details:details-of-error Displays the error details. • Type of error:cause-of-error Displays the cause of the error.
YKEWAIT Command Applies to Business Copy for Mainframe, Continuous Access Synchronous for Mainframe, Continuous Access Synchronous for Mainframe with the HyperSwap attribute, Continuous Access Asynchronous for Mainframe, and Continuous Access Journal for Mainframe.
SUSPEND The command waits until all the copy pairs in the group reach the SUSPOP or SWAPPING status. However, if the status of any copy pair changes to the SIMPLEX, SUSPER, SUSPCU, HOLD, HOLDER, HOLDTRNS, NODELTA, CONSLOST, or INVALID status, the YKEWAIT command terminates abnormally with return code 8. SIMPLEX The command waits until all the copy pairs in the group reach the SIMPLEX status.
NOINVALIDCHECK Processing continues even when the status changes to anything other than the status specified by the GOTO parameter (invalid statuses). If this parameter is specified, and the status does not change to that specified in the GOTO parameter, command processing will continue until the timeout time specified in the TIMEOUT parameter is reached. The invalid statuses in Table 108 (page 205) differ depending on the value specified in the GOTO parameter.
Specify this parameter to monitor copy groups by monitoring the status of either P-VOLs or S-VOLs. When the TO parameter is specified, the copy group container is not checked for EXCTG registration information. • PRIMARY Monitors the status of P-VOL during copy group definition. • SECONDARY Monitors the status of S-VOL during copy group definition. VOLUNIT Usually, information is obtained for each CU, but when this parameter is specified, information is obtained for each volume.
1 If a time-out has taken place, use the YKQUERY command to check the status of the copy pair. If there is a copy pair where a transition has not taken place, the S-VOL of the copy pair might be ONLINE. Place it OFFLINE and re-execute. In addition, for CG containers specified by EXCTG ID, check if the journal group has been registered in EXCTG.
NOTE: • The execution of this command does not check if the configuration of the copy groups specified in the copy group definition file is supported. Therefore, an error could result when you specify, by using the YKIMPORT command, a CSV file created by this command. If an error occurs, check if the configuration of the copy groups in the CSV file is supported. • The pair information CSV file is created even if an error occurs during creation of the EXCTG information CSV file.

Table 118 YKLOAD Command Return Code List Return Code Meaning 0 The command completed normally. 4 Unknown XML attributes or elements encountered in input file. 8 Unable to resolve device number for S-VOL in copy pair. 12 Unable to resolve volume serial number for P-VOL in copy pair. 16 Unable to resolve device number for P-VOL in copy pair. 36 Terminating due to invalid XML structure encountered in input file, or system symbols are not defined correctly.
The message structure is initialized when the CLI command with the same name as the MSG parameter is specified. {FORWARD|REVERSE} Specify the copy direction. FORWARD The command makes a copy pair directed from the primary site to the secondary site. REVERSE Makes a copy pair in the reverse direction, from the secondary site to the primary site. NOCOPY Applies to Continuous Access Synchronous for Mainframe, Continuous Access Asynchronous for Mainframe, and Continuous Access Journal for Mainframe.
NOTE: • Do not dissolve copy pairs during a planned outage. • In 4x4x4 Delta Resync configurations, when all copy pairs in EXCTG whose copy direction is from the primary site to the remote site are dissolved, the journal groups whose copy direction is from the local site to the remote site are also dissolved from EXCTG registration.
NOTE: • If ONLINE(YES) is specified, volume corruption might occur because a copy pair can be made even if the S-VOL is being used. Thus, consideration with respect to volume operation is required, such as limiting operation to periods when the S-VOL is not being used. • If transition to HOLD status is not performed, this might indicate an environment in which differentials cannot be maintained in the journal.
Format YKQEXCTG 1STEM(stem-name-1) 1MSG(stem-name-2) 1TO({SECONDARY|PRIMARY}) Function This is a TSO/E command. Information about the copy group container with the specified EXCTG ID is acquired from the supervisor DKC at the site specified for the TO parameter.

ATTIME(timevalue) If you use the ATTIME suspend function, specify the time at which suspend processing is performed. This parameter is valid for copy groups specified by consistency group ID. If you do not use the CAJ ATTIME suspend function, this parameter cannot be specified for a remote storage system. You must use the CAJ ATTIME suspend function for a copy group in which the P-VOLs are Non Gen'ed volumes. If you do not use the CAJ ATTIME suspend function, an I/O error will occur.
NOTE: When you specify the time using ATTIME parameter, note the following: • Do not specify a time value earlier than the command execution time. • The processing might be suspended when the specified time is reached during command execution. Take the command execution time into consideration when you specify the time. • Do not specify a time value larger than the command execution time plus 65,536 minutes.
GENID(generation-id) ~ <2-digit hexadecimal number><<00>> Applies to Business Copy for Mainframe, Continuous Access Asynchronous for Mainframe. Specify a generation ID. The default value (used when this parameter is omitted) is 00. Generation IDs can be used as a generation number used for identifying the generation of backups. For example, generation IDs are useful when you need to maintain consistency between multiple storage systems.
Table 134 Operation When the ATTIME Suspend Time Is Canceled in BC (continued) Target storage system or copy group Setting of the ATTIME suspend time CAJ ATTIME suspend time Operation when the ATTIME suspend time is canceled NORMAL ATTIME CAJ ATTIME suspend suspend time time NORMAL ATTIME suspend time canceled because it has not been set.1 canceled because it has not been set.1 • Storage system that Specified is directly connected to a host -- The CAJ ATTIME suspend time is canceled.
QUICK Applies to Business Copy for Mainframe. Suspends in the QUICK mode. The S-VOL can be read or written even when data is being copied. When this parameter is not specified, the S-VOL can be read or written after data copying, and transition to the SUSPOP status have finished.
suspension will be the same as that used when the FLUSH parameter is specified. When neither FORWARD parameter nor REVERSE parameter are specified, the status of copy pairs become SUSPOP. The copy direction is not changed at the time of RESYNC. SVOL ({PROTECT|PERMIT}) Specify whether writing to the S-VOL is permitted or protected after a volume is suspended (SUSPOP). When this parameter is not specified, the value specified in the ISPF panel is assumed.
NOTE: • If more than one of the ATTIME, CANCEL, DRAIN, PURGE, FLUSH, QUICK, FORWARD, and REVERSE parameters is specified, the last specified parameter takes effect. • The YKSUSPND command terminates successfully when the instruction to the copy pair succeeded. Even if the YKSUSPND command has terminated with return code 0, the copy pair might not be in the SUSPOP or SWAPPING status.
Table 135 YKSUSPND Command Return Code List (continued) Return Code Meaning • When the copy pair corresponding to the device number specified with the DEVN parameter is not found. • When the VOLUNIT parameter or DEVN parameter, and the PURGE parameter are specified for a CAJ at the same time. • For a CAA, when an attempt to cancel the ATTIME suspend time for the remote storage system was made. 128 The command terminated abnormally. The user does not have permission to execute this command.
SUSPEND The command waits until all the copy pairs in the group reach the SUSPOP status. However, if the status of any copy pair changes to a status other than a suspend status (SUSPOP, SUSPCU, or SUSPER) or TRANS, the YKWATCH command terminates abnormally with return code 8. SIMPLEX The command waits until the copy pairs reach the SIMPLEX status. When any copy pair takes a status other than SIMPLEX, however, the YKWATCH command terminates abnormally with the return code 8.
NOTE: • In some configurations such as when CA and BC share volumes or a 1 to n (n is greater than 2) configuration of BC, the status transitions of each copy pair might not be correctly monitored. • When using a copy pair on a remote site (a site that is not channel-connected directly from the local host), the YKWATCH command cannot monitor the status transition of the copy pair on the remote site. Use the YKEWAIT command.
Function This is a REXX function that is called from within a REXX script. This command outputs the specified message ID and message text to the OS console. Parameters type Specify the type of message to be output. The message is output by using the destination indicating a code that corresponds to the specified type. Specify one of the following types: • I Specify this for a message that reports information. The message is output in by using the destination indicating code 11.

4 BCM Monitor Parameter Files This chapter describes the BCM Monitor Parameter Files and the YKMONOPT and YKMONCG files. Overview of BCM Monitor Parameter Files This section describes the parameter files used with BCM Monitor. Content of the BCM Monitor Parameter Files “Parameter Files Used with BCM Monitor” (page 363) lists and describes the parameter files used with BCM Monitor.
If both a continuation symbol and a comment symbol are specified on the same line, the comment symbol takes precedence. No more than one parameter can be specified per line. When a continuation symbol is used, the next line is treated as part of the same line. Maximum number of characters per line Even with the use of continuation symbols, the maximum number of characters per line is 32,760.
Information to be set This parameter file sets the option information required for starting BCM Monitor. Parameters CYCLETIME=cycle-time ~ ((10 to 999999))<<300>> Specifies the cycle time in seconds for monitoring the copy group status. The following figure shows the concept of the copy group status monitoring cycle. If the specified value is from 0 to 9, 10 seconds is used for CYCLETIME.
Specifies the default error action to be used when no error action is specified in the ACTION parameter in the YKMONCG file. SKIPONLY Skips the cycle where an error occurred, but starts monitoring again from the next cycle. STOP Places the monitoring status of all copy groups specified in the CGID parameter to INACTIVE EXIT(return-code) ~ ((0 to 4095)) Stops BCM Monitor with the specified return code.
Figure 101 Structure of Parameters in the YKMONCG File NOTE: • The parameters can be specified for each copy group (CGID). • If a copy group parameter that is not a CGID parameter is specified more than once under a single CGID parameter, the last time the parameter is specified takes effect. • You can specify more than one STATUS parameter under a single CGID parameter. • An error occurs if more than one CGID parameter with the same copy group ID is specified.
Copy Group Parameters Format CGID=copy-group-ID CGPREFIX=prefix CGDAD=DADID [CGROUTE=route-list-ID[,{route-label|'*'}]]] [CGMONSTAT={ACTIVE|INACTIVE}] [CGSTARTUPSTATUS=startup-status,startup-action[,NOCANCEL]] Information to be set You can specify the startup status of a copy group that you want to monitor, and the startup action to be executed if the copy group is not in startup status.
INACTIVE Does not montior the copy group. CGSTARTUPSTATUS=startup-status,startup-action[,NOCANCEL] If this parameter is specified and the copy group status is not the specified startup status when BCM Monitor starts, the specified startup action is executed. The processing of this parameter is also for copy groups that has ACTIVE or INACTIVE specified for the CGMONSTAT parameter.
NOCANCEL Does not execute the YKSUSPND command with the CANCEL parameter specified. You can specify this value only if you specified DUPLEX as the startup status. Processing for Changing to the Startup Status This section describes the processing of changing the copy group to the startup status when ADJUST is specified for the CGSTARTUPSTATUS parameter.
Table 163 Processing for the Specified Startup Status (continued) Specified startup status Copy pair status Processing CONSLOST SUSPOP Executes the following commands: SUSPCU • YKRESYNC SUSPVS SUSPOP All SUSPOP • YKEWAIT GOTO(DUPLEX) Does nothing. SUSPVS SIMPLEX SWAPPING Places the monitoring status of all copy groups specified in the CGID parameter to INACTIVE.
Table 163 Processing for the Specified Startup Status (continued) Specified startup status Copy pair status Processing CONSLOST Executes the following commands: HOLDER • YKRESYNC PREPARE • KEWAIT GOTO(HOLD) Action Parameters An action parameter specifies an action for the copy group. Format [STATUS=target-status,ACTION=action;[error-action;]]... Information to be set Specifies the target status, action, and error action for the copy group.
Table 164 Combinations of Target Statuses and Actions That Can Be Specified (continued) Target status Action SWAPPING Y Y Y Y Y N N N Y Y Y Y Y Y Y Y Y Y N Y Y Y DUPLEX Legend Y = This combination can be specified. N = This combination cannot be specified. Parameters target-status Specifies the status of the copy group on which the action is to be executed. For the specifiable values, see “Combinations of Target Statuses and Actions That Can Be Specified” (page 372).
EXIT(return-code) ~ ((0 to 4095)) Stops BCM Monitor with the specified return code. HP recommends hat you specify a value other than 0, 4, 8, or 12 because these numbers are already used as BCM Monitor return codes. REPORT(copy-group-ID[,{SUMMARY|DETAIL|STATS|RPO}[,{CONS|ERROR|STATUS|INFO}]]) Outputs report information for the specified copy group. {SUMMARY|DETAIL|STATS|RPO} Specifies the type of report information: SUMMARY Outputs summary information about the copy group.
Specifies the YKRESYNC command parameters. The STEM and MSG parameters are ignored even if they are specified. For details on the specifiable parameters, see the description of parameters in “YKRESYNC Command” (page 237). SUSPEND(copy-group-ID[,'command-parameter']) Executes the YKSUSPND command with the specified command parameters on the specified copy group. command-parameter ~ Specifies the parameters of the YKSUSPND command.
STATUS Outputs as a YK8300I message, which reports a status. INFO Outputs as a YK8400I message, which indicates information. STOPPOINT(label-name) ~

5 Parameters for YKBTSCAN This chapter describes the parameters for YKBTSCAN. Functionality YKBTSCAN executes local scans by batch. YKBTSCAN locally scans the volume of the device number or volume serial number that you entered from SYSIN, and then creates a disk configuration definition file for the detected volume. If the disk configuration definition file already exists, YKBTSCAN updates the file by adding the newly obtained volume information to the existing disk configuration definition file.
DAD(device-address-domain-ID)~ Specify the current host's device address domain ID (host device address domain ID). For details about the maximum length that can be specified, see “Names of configuration files” (page 306). DEVN(nnnn[:nnnn][,nnnn[:nnnn]]...)~ <4-digit hexadecimal number> Specify the device number of a volume to be scanned. To specify a range of device numbers, insert a colon between the first and the last device numbers for scanning.
For scanning the volumes with the device numbers ranging from 1100 to 1105 and the device number 1107 PREFIX(PREFIX1) DAD(DAD1) DEVN(1100:1105,1107) For scanning the volumes with the volume serial numbers VOL001, VOL005, and VOL009, and the volume serial numbers ranging from VO020 to VOL030 PREFIX(PREFIX1) DAD(DAD1) VOLSER('VOL001','VOL005','VOL009') VOLSER('VOL020':'VOL030') For scanning the volumes with the device numbers ranging from 1100 to 1105, and the volumes with the volume serial numbers ranging
