Dell SRDF Adapter for VMware Site Recovery Manager 10.1.0.0 Release Notes

This section provides the procedures for configuring the Dell SRDF Adapter to work with Site Recovery Manager.

Configuring a locally attached PowerMax array

When configuring a PowerMax array that is locally attached to the server running VMware Site Recovery Manager, specify Local in the SYMAPI Server field in the Array Manager configuration wizard of VMware Site Recovery Manager.

Cascaded and concurrent configurations

Follow the guidelines in the table below for cascaded and concurrent configurations.

Configuring SRDF/Star

SRDF/Star is a data-protection and failure-recovery solution that covers three geographically dispersed data centers in a triangular topology.

Consider the following when configuring SRDF/Star:

• Reconfiguration of the SRDF/Star topology from Concurrent to Cascaded, and from Cascaded to Concurrent, is not a supported workflow. If reconfiguration is needed, it has to be done outside SRA.
• The SRDF/Star commands in SRA might take multiple hours. It depends on the amount of replication data.
• SRA supports the following valid SRDF/Star states for device discovery:

  Table 2. Valid SRDF/Star states for device discoveryThis table lists valid SRDF/Star states for device discovery.

  SRDF/Star state	Sync target site state	Async target site state
  Protected	Protected	Protected
  Tripped	PathFailed	PathFailed
  Tripped	PathFailed	Protected
  Tripped	Protected	PathFailed
  Unprotected	Disconnected	Protected
  Unprotected	Connected	Protected
  Unprotected	Protected	Protected
  Unprotected	Halted	Halted
  Unprotected	Isolated	Protected
  Unprotected	Protected	Isolated
  Unprotected	Isolated	Disconnected

• SRA supports the following SRDF/Star states for Site Recovery Manager operations, such as Recovery and Test Recovery:

  Table 3. Valid SRDF/Star states for recovery and test recovery operations for sync target siteThis table lists valid SRDF/Star states for recovery and test recovery operations for sync target sites.

  SRDF/Star state	Sync target site state	Async target site state
  Protected	Protected	Protected
  Tripped	PathFailed	PathFailed
  Tripped	PathFailed	Protected
  Tripped	Protected	PathFailed

• Only if site A is down, or partitioned from site B, can the mode of operation change from Cascaded Star to Concurrent Star. To return the configuration to its original Cascaded Star mode, you must perform a reconfiguration, outside of SRA.

  Table 4. Valid SRDF/Star states for recovery and test recovery operations for async target site This table lists valid SRDF/Star states for recovery and test recovery operations for async target sites.

  SRDF/Star State	First target site state	Second target site state
  Protected	Protected	Protected
  Tripped	PathFailed	PathFailed
  Tripped	PathFailed	Protected
  Tripped	Protected	PathFailed
  Unprotected	Protected	Connected

• Only if Site B is down, can the mode of operation change from Cascaded Star to Concurrent Star. To return the configuration to its original Cascaded Star mode, you must perform a reconfiguration, outside of SRA.
