ANR4799E
The server-free operation type from device source name through data mover data mover name to device target name failed after issue.

Explanation

The server-free operation failed after issuing the SCSI command. This might be because the value for the HBA (host bus adapter) scatter-gather list is not large enough.

System action

The server does not perform the server-free operation. The server will attempt either a LAN-free or classic LAN operation.

User response

Perform either, or both, of the following steps to allow server-free operations:
  • Change the serverfree batchsize to a lower value.
  • Change the MAXIMUMSGLIST value for the HBA within the Windows registry, or run the DSMMAXSG utility to change the MaximumSGList value to 0x41(65) for all HBAs.
