restoring database on a test server: ERROR: slave communication error with ASM

I am gettng this error while trying to restore an exadata/asm database on a new standalone linux filesystem.

RMAN target / nocatalog to connect (using the restored controlfile, no catalog)

it is failing at the stage when 'restore database;'  command.

The original backups are performed daily on exadata-Qrack/asm/rac- 'physical-copy'  (rman scripts with no catalog)

The backup files moved to test server folder

Restore/recovery is done on test server standalone (no asm, no catalog)

---

using the following rman script:

RUN
{
  # allocate a channel to the tape device
  ALLOCATE CHANNEL c1 DEVICE TYPE disk FORMAT   '/home/oracle/fdm_backup_files/%d_FULL_%Y_%M_%D_%t_%u_%s_%p';
