Impact on the System

  • When HyperMetro or synchronous remote replication is configured between storage arrays, degrading the replication link may degrade system performance and reliability, or even affect host services.
  • When asynchronous remote replication is configured between storage arrays, degrading the replication link may affect the synchronization speed.

Possible Causes

  • Packet loss or bit errors occur on the local or remote port.
  • Packet loss, disorder, or bit errors occur on the switch.
  • The service load on the local or remote array is too heavy.

Procedure

  1. Check whether bit errors and packet loss occur on the local and remote replication link ports.

    1. If yes, replace the optical module. If the alarm persists=> 1.2.
    2. Replace the cable. If the alarm persists=> 1.3.
    3. Replace the interface module. If the alarm persists=> Step2.
    4. If no bit error or packet loss occurs=> Step2.

  2. Check whether the switch related to the replication link is normal.

    1. If packet loss, disorder, or bit errors occur on the switch, rectify the fault. If the alarm persists=> Step3.
    2. If the switch is normal=> Step3.

  3. Check whether the service load on the local and remote arrays is too heavy.

    1. If yes, contact technical support engineers for capacity expansion and service optimization.
    2. If no, collect related information and contact technical support engineers.
