14.3.1 Metro Mirror management with ICKDSF
Table 14-2 lists the Metro Mirror commands available with ICKDSF.
Table 14-2 ICKDSF Metro Mirror commands
All commands have to be addressed to a device that is either online or offline to the system
where the job is submitted. For offline volumes, the ICKDSF job must address the volumes
directly by specifying
UNITADDRESS , as shown in Example 14-13.
Example 14-13 Addressing offline volumes
//DELPTHRV JOB (ACCT),'DEL REVRSE PPRC PATH',
// CLASS=A,MSGCLASS=H
//STEP01 EXEC PGM=ICKDSF
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
PPRCOPY DELPATH -
UNITADDR(3000) -
..................
Online volumes cannot be addressed directly and DD statements with the volume serial
number must be used. This assures access to the volume serial number of the volume,
regardless of the real address of the volume; see Example 14-14.
Example 14-14 Addressing online volumes
//DELPAIR1 JOB (ACCT),'ICKDSF DELPAIR',
// MSGCLASS=X,NOTIFY=&SYSUID,MSGLEVEL=(1,1)
//**************************************
//STEP01 EXEC PGM=ICKDSF
//SYSPRINT DD SYSOUT=*
//VOL1 DD UNIT=3390,VOL=SER=DS6400,DISP=SHR
//SYSIN DD *
PPRCOPY DELPAIR DDNAME(VOL1) PRI(X'0002',AAVCA,X'00') -
SEC(X'0003',AAVCA,X'00') LSS(X'00',X'01')
