	The DCL lexical F$GETDVI with item "STS" will return the status information of the specified device. $ write sys$output f$getdvi("$1$dua30:","STS") returns 16 So what does 16 mean? Well, execute: $ library sys$library:lib.mlb/extract=$ucbdef/output=ucbdef.txt Edit ucbdef and look for 16. You get $EQU UCB$M_ONLINE 16 So my device is online. This is a simple case. From a stars article entitled "Detecting Mount Verification with F$GETDVI" it states: A disk is in a "mount verification has timed out" state if the following conditions are true: o the disk is mounted o UCB$V_MNTVERIP in the STS field is clear (bit 14) o UCB$V_VALID in the STS field is clear (bit 11) o the ACP type (from DVI$_ACPTYPE) is either F11V1 or F11V2 A disk is in "mount verification in progress" if the following conditions are true: o the disk is mounted o UCB$V_MNTVERIP in the STS field is set (bit 14) DVI$_STS and STS return a vector which is documented in the $UCBDEF module of the LIB.MLB macro library.

    So what does 16 mean?  Well, execute:
    
    $ library sys$library:lib.mlb/extract=$ucbdef/output=ucbdef.txt

    So my device is online.  This is a simple case.              
    
    From a stars article entitled "Detecting Mount Verification with
    F$GETDVI" it states:
    
    A disk is in a "mount verification has timed out" state if the         
    following conditions are true:                                     
                                                                      
      o  the disk is mounted                                           
      o  UCB$V_MNTVERIP in the STS field is clear (bit 14)               
      o  UCB$V_VALID in the STS field is clear (bit 11)                    
      o  the ACP type (from DVI$_ACPTYPE) is either F11V1 or F11V2            
                                                                              
    A disk is in "mount verification in progress" if the following              
    conditions are true:                                   
                                                 
      o  the disk is mounted                                              
      o  UCB$V_MNTVERIP in the STS field is set (bit 14)                
                                             
    DVI$_STS and STS return a vector which is documented in the $UCBDEF        
    module of the LIB.MLB macro library.
