    Vproc Manager Command

    Description

    STATUS

    Provides STATUS information about vprocs.

    INITVDISK <vproc ID>

    Initializes the DBS File System on a vdisk. It applies only to vprocs with a status of NEWPROC or FATAL AMP. Valid vproc IDs are decimals ranging from 0 to 16383. Hex numbers can be used with a trailing “x.”

    RESTART [TPA] [NODUMP | DUMP = {YES, NO}][<RestartKind] [<comment>]

    Forces different types of DBS restarts:

  • NODUMP (the default) indicates no system dump.
  • DUMP = YES indicates a system dump.
  • DUMP = NO is equivalent to NODUMP.
  • ValidRestartKind is either COLD or COLDWAIT.
  • Comment specifies the reason for the restart.
  • BOOT <vproc ID>

    Reinitialize the AMP disk before an all-table rebuild and starts the DBS partitions on the specified AMP. It applies only to vprocs with a VprocState of FATAL and a ConfigStatus of Down.

    SET

    Sets the state of a vproc to either ONLINE, OFFLINE, or FATAL.
