Keeping the GAD Pair Information

During a snapshot backup operation on the Hitachi Vantara CCI storage array, if the source volume is a global-active device (GAD) paired volume, then the raidscan command queries the other end of the GAD pair. On active secondary volumes, this command fails to get the GAD pair details about the primary array. Because the command fails, the snapshot operation cannot continue on either end of the GAD pair.

To resolve this problem, use the sCVHDSArrayGadPairedWith_<ArraySerial> additional setting. The sCVHDSArrayGadPairedWith_<ArraySerial> additional setting keeps the information about the GAD pair.

Procedure

• To the host computer, add the sCVHDSArrayGadPairedWith_<ArraySerial> additional setting as shown in the following table.
