The following figure shows the TC/SI configuration example with cascade pairs.



Example of CCI commands with HOSTA and HOSTB

  • Designate a group name (Oradb) on TrueCopy environment of HOSTA.
    # paircreate  -g Oradb  -vl
  • Designate a group name (Oradb1) on ShadowImage environment of HOSTB. When the command execution environment is not set, set HORCC_MRCF.

    For C shell: # setenv HORCC_MRCF 1

    For Windows: set HORCC_MRCF=1

    # paircreate -g Oradb1 -vl

    These commands create pairs for all LUs assigned to groups Oradb and Oradb1 in the configuration definition file (four pairs for the configuration in the above figures).

  • Designate a group name and display pair status on HOSTA.
    # pairdisplay -g oradb -m cas
    Group   PairVol(L/R) (Port#,TID,LU-M),Seq#,LDEV#.P/S,Status, Seq#,P-LDEV# M

    oradb2  oradev22(R) (CL1-D , 2,  2-1)30053  269..SMPL  ----,-----   ----  -
    oradb   oradev2(R)  (CL1-D , 2,  2)  30053  269..S-VOL COPY,-----    267  -

Example of CCI commands with HOSTB

  • Designate a group name (oradb) on TrueCopy environment of HOSTB.
    # paircreate  -g Oradb  -vr
  • Designate a group name (Oradb1) on ShadowImage environment of HOSTB. When the command execution environment is not set, set HORCC_MRCF.

    For C shell: # setenv HORCC_MRCF 1

    For Windows: set HORCC_MRCF=1

    # paircreate -g Oradb1 -vl

    This command creates pairs for all LUs assigned to group Oradb1 in the configuration definition file (four pairs for the configuration in the above figures).

  • Designate a group name and display pair status on TrueCopy environment of HOSTB.
    # pairdisplay -g oradb -m cas
    Group   PairVol(L/R) (Port#,TID,LU-M),Seq#,LDEV#.P/S,Status, Seq#,P-LDEV# M
