Figure 2.40 Hitachi TrueCopy Remote Configuration Example

Example of CCI commands with HOSTA:
Designate a group name (Oradb) and a local host P-VOL a case.
# paircreate -g Oradb -f never -vl
This command creates pairs for all LUs assigned to group Oradb in the configuration
definition file (two pairs for the configuration in Figure 2.40.
Designate a volume name (oradev1) and a local host P-VOL a case.
# paircreate -g Oradb -d oradev1 -f never -vl
This command creates pairs for all LUs designated as oradev1 in the configuration
definition file (CL1-A,T1,L1 and CL1-D,T2,L1 for the configuration in Figure 2.40).
Designate a group name and display pair status.
# pairdisplay -g Oradb
Group PairVol(L/R) (P,T#,L#), Seq#, LDEV#..P/S,
oradb oradev1(L) (CL1-A, 1,1) 30053
oradb oradev1(R) (CL1-D, 2,1) 30054
oradb oradev2(L) (CL1-A, 1,2) 30053
oradb oradev2(R) (CL1-D, 2,2) 30054
Example of CCI commands with HOSTB:
Designate a group name and a remote host P-VOL a case.
# paircreate -g Oradb -f never -vr
This command creates pairs for all LU designated as Oradb in the configuration
definition file (two pairs for the configuration in Figure 2.40).
Designate a volume name (oradev1) and a remote host P-VOL a case.
# paircreate -g Oradb -d oradev1 -f never -vr
This command creates pairs for all LUs designated as oradev1 in the configuration
definition file (CL1-A,T1,L1 and CL1-D,T2,L1 for the configuration in Figure 2.40).
Designate a group name and display pair status.
# pairdisplay -g Oradb
