StorageTek Disabling a VOLATTR Definition, Volattr, 144VM/HSC 6.0 System Programmer’s Guide

VOLATTR

If you enter any VOLATTR statement that globally defaults to all volumes (i.e., VOLATTR SER(*) REC(18)), you must precede this statement with VOLATTRs specifying the cleaning cartridges for each type of transport defined in the ACS. Cleaning cartridges for longitudinal drives should be defined as MED(S); for helical drives, MED(DD3D); for 9840 drives, MED(STK1U).

If global defaults are used to specify RECtech for large ranges of volumes, specify both MEDia and RECtech on all preceding VOLATTR statements. Otherwise, for a given VOLSER, the MEDia may be obtained from an earlier statement.

In the following example, the media type obtained from an earlier statement results in a default RECtech of STK1R. Then, the global statement that follows specifies a global RECtech of 36track, which is incompatible with the earlier statement.

VOLATTR SERIAL(EAG000-EAG999) MEDIA(STK1R)

VOLATTR SERIAL(*) RECTECH(36TRACK)

Disabling a VOLATTR Definition

Use the following procedure to disable a VOLATTR definition.

1.Edit the definition data set containing the current VOLATTR statements.

2.Delete the parameters of the VOLATTR statement you want to disable, or delete or comment out the VOLATTR statement.

3.Issue the VOLDEF command to reload the definition data set.

With the modified definition data set in effect, the HSC searches the remaining VOLATTR statements to determine the media type and recording technique for a volume.

To disable all VOLATTR definitions, load a definition data set that contains only the statement VOLATTR SERIAL(*). Refer to Table 7 on page 148 and Table 8 on page 150 to see a list of VOLATTR media and recording technique default values.
