Figure 1 shows the entries in VATLSTxx that define the mount and use attributes. Table 1 describes the fields in more detail.
In the first entry in Figure 1, a volume whose serial number is 30565A is to be mounted on a 3330 and marked permanently resident. The volume's use attribute is to be private. A mount message is to be issued if the volume is demounted. The optional information, PAGING VOLUME, appears in installation printouts but does not affect VATLST processing.
In the second entry in the example, volumes with serial numbers that include the character string "TSO" are to be mounted on any DASD and reserved. The volumes' use attribute is to be public. Because you specified a generic volume serial number, the system does not issue a mount message for un-mounted volumes. The optional information, TSO, appears in installation printouts but does not affect VATLST processing.
In the third entry, volumes with serial numbers included in the 305%* specification, are to be mounted on a 3380 and marked permanently resident. The use attribute is to be private.
In the fourth entry, a specific volser name, 30565B, contains an “S” in column 7, indicating that the volser is specific. However, error message IEA855I will be issued because the volser does not contain either of the special characters, “%” or “*”. The “S” should only be coded for specific volsers containing special characters.
| Parameter | Column | Meaning and Use | Value Range | Default Value |
|---|---|---|---|---|
| volume serial | 1-6 | Specifies either the direct access volume with mount and use attributes to be set, or a generic volume serial number. The volume serial number must begin at the first character position in the record. | 1 to 6 alphameric characters plus special characters % and *, left justified in the field and padded with blanks at right to occupy six columns. | None |
| specific vol. ser. identifier | 7 | "S" specifies that the entry is a specific volume serial number, not a generic one. Code the "S" only when your volume serial number has an asterisk or percent sign in it and you do not want the system to process it as a generic entry. Code a comma when the volser is a specific volser without the special characters or the volser is a generic volser. | S or , | None |
| mount attribute | 8 | Specifies whether the volume is to be permanently resident
or reserved. Default is assigned if any character other
than 1 is specified.
|
0 or 1 | 0 |
| use attribute | 10 | Specifies whether the volume is to be defined as storage, public,
or private. The default is assigned if any character other
than 0, 1, or 2 is specified.
|
0-2 | 1, unless the VATDEF operand specifies a different default. |
| device type | 12-19 | Specifies the device type, such as 3380. Up to eight characters may be specified, but the first character must start at column 12. Only supported device types that were defined through HCD are acceptable. This parameter indicates the basic device but does not denote special features, such as track overflow. An asterisk "*" in column 12 indicates a generic device type. | Up to 8 characters, left justified within the field, and padded with blanks at the right to occupy eight columns. | None |
| mount message suppression | 21 | Specifies whether mount messages should be issued
for the volume if it is not already mounted. This parameter is ignored
for volumes that are defined with generic VATLST entries.
|
N, blank, or any character. | Blank, indicating that mount messages should be issued. |
| optional information | 23-80 | Contains optional, installation-defined information (for example, an eye-catcher or brief comment) to be included in installation printouts. The system does not use this information. | Not applicable. | None |
