    • If the pair status is PAIR, PSUS, or PSUE, the pair synchronization rate shows the rate that current S-VOL data matches that of the next generation of the S-VOL. If the S-VOL is the latest one, the synchronization rate is computed by comparing the S-VOL with the P-VOL.
    • If the pair status is COPY, PSUS(SP), RCPY, or SMPL(PD), the progress rate of each process is displayed.
    • For Thin Image pairs with the cascade attribute disabled, the pair synchronization rate that the current S-VOL data matches that of the next generation of the S-VOL is displayed. If the S-VOL is the latest one, the synchronization rate is computed by comparing the S-VOL with the P-VOL.

      To display the progress rate, enable Display Progress Rate of the system option #17 in the Edit Local Replica Options window.

      • If the pair status is COPY, RCPY, or SMPL(PD), the progress rate for each process is displayed.

SI/TI System Options table

The following table lists the items in this table on the Edit Local Replica Options window.

Item

Description

System Option

Displays the system options. The number next to each item is the system option number.

Values:

  • Swap & Freeze (1) Quick Restores and then saves the current data. Used with the Quick Restore, inhibits the Update Copy operation after performing Quick Restore, and the paired S-VOL in "PAIR" status is not updated.
  • Host I/O Performance (2) Use this option to give weight to I/O response rather than the copy time. This option controls copy operations and improves the host I/O response.
  • Nondisruptive Migration Data Consistency (16) Use this option to keep the latest data in the migration source storage system instead of distributing data in both the destination and source storage systems during data migration.
  • Display Progress Rate (17) For Thin Image pairs with the cascade attribute disabled, the pair synchronization rate displayed on HDvM - SN (Synchronization Rate (%) in the View Pair Synchronization Rate window) or CCI is switched to the progress rate. However, even if this option is enabled, the synchronization rate is displayed only when the pair status is COPY, RCPY, or SMPL(PD). If this option is enabled, the following information is displayed depending on the pair status:
    • If the pair status is COPY, RCPY, or SMPL(PD), displays the progress rate for each process.
    • If the pair status is PAIR, PSUS, or PSUE, displays the pair synchronization rate that the current S-VOL data matches that of the next generation of the S-VOL. If the S-VOL is the latest one, the synchronization rate is computed by comparing the S-VOL with the P-VOL.
  • Copy Pace Ext. Slower1 (20), Copy Pace Ext. Slower2 (21), Copy Pace Ext. None (22) Reducing the copy volume in "PAIR" status curbs the influence to the I/O performance of the host server. This item is available to all pairs in "PAIR" status. The order of Copy Pace Ext. Slower1, Copy Pace Ext. Slower2, and Copy Pace Ext. None determines the host server’s I/O performance.
  • Quick/Steady Split Multiplexing (ShadowImage/ShadowImage for Mainframe) (24) Accelerates ShadowImage pair split. The multiplicity (the number of jobs for which copy processing can be executed concurrently) of copy processing for each pair is changed from 1 to 24.
  • Reverse Copy Multiplexing (ShadowImage/ShadowImage for Mainframe) (25) Accelerates resynchronization (secondary to primary) of ShadowImage pairs. The multiplicity (the number of jobs for which copy processing can be executed concurrently) of copy processing for each pair is changed from 1 to 24.
  • Normal Resync Multiplexing (ShadowImage/ShadowImage for Mainframe) (26) Accelerates resynchronization (primary to secondary) of ShadowImage pairs. The multiplicity (the number of jobs for which copy processing can be executed concurrently) of copy processing for each pair is changed from 1 to 24.
  • Disable the alert notification of shared memory space warning (30) Inhibits the alert notification of SIM reference code 603000.

  • Host I/O Performance (2)Use this option to give weight to I/O response rather than the copy time. This option controls copy operations and improves the host I/O response.
  • FC Slower Copy1 (FCv2 or FCSE only) (3)Reduces the multiplicity of background copy into half.
  • FC Slower Copy 2 (FCv2 or FCSE only) (4)Reduces the multiplicity of background copy into quarter.
  • Nondisruptive Migration Data Consistency (16)Use this option to keep the latest data in the migration source storage system instead of distributing data in both the destination and source storage systems during data migration.
  • FC Ext. Slower Copy1 (17)Inhibits background copy and improves host I/O response when the operating ratio of the MP unit (FCv2 or FCSE S-VOL or T-VOL is allocated) exceeds 65%.
  • FC Ext. Slower Copy2 (18)Inhibits background copy and improves host I/O response when the operating ratio of the MP unit (FCv2 or FCSE S-VOL or T-VOL is allocated) exceeds 50%.
  • Copy Pace Ext. Slower1 (20), Copy Pace Ext. Slower2 (21), Copy Pace Ext. None (22)Reducing the copy volume in the "DUPLEX" status curbs the influence to the I/O performance of the host server. This item is available to all pairs in "DUPLEX" status. The I/O performance of the host server is improved in order of Copy Pace Ext. Slower1, Copy Pace Ext. Slower2, and Copy Pace Ext. None.
