DISMOUNT
DISMOUNT
Releases a volume set that was explicitly reserved by the user with a MOUNT or VSRESERVE
command. The equivalent native mode command is VSRELEASE. (Native Mode)
Syntax
DISMOUNT[{ * volumesetname }][.groupname[.acctname]]
Parameters
* or <blank> Specifies the home volume set for the group and account specified, or for
the logon group and account if groupname or groupname.acctname is not
specified.
volume- setname An artificial component of a volume set name used to maintain backward
compatibility with MPE V/E. The volumesetname can be a maximum of 8
characters.
groupname Used only for compatibility with MPE V/E. The groupname can be a
maximum of 8 characters.
acctname Used only for compatibility with MPE V/E. The acctname can be a
maximum of 8 characters.
Operation Notes
The DISMOUNT command allows you to release a volume set that you explicitly reserved
using the MOUNT or VSRESERVE command. You can request a release only for a volume set
that you have reserved; you cannot alter the status of the volume set for other users.
Volume sets in MPE/iX are not tied to groups and accounts (this differs from the MPE V/E
scheme of disk partitioning).
The naming convention for MPE/iX volume sets differs from the naming convention for
MPE V/E private volumes. MPE/iX volume set names may consist of any combination of
alphanumeric characters, including the period (.) and the underbar (_). The name must
begin with an alphabetic character and consist of no more than 32 characters.
Table 3-3 is a comparison of naming conventions between the MPE/iX VSxxxxxx and MPE
V/E xxxMOUNT commands
