Volume attribute list that defines the "mount" and
"use" attributes of direct access volumes. Multiple
lists named VATLSTxx replace PRESRES.
Parameter in IEASYSxx
VAL=(aa,bb, . . .)
Do not specify a list at
a given IPL that contains entries for volumes that will not be
mounted unless "N" is specified to suppress the mount
message. Specifying "Y" will cause unmounted volumes
to require operator intervention
with resultant delay.
A private volume
is allocated only to a specific volume request.
volume is allocated to temporary, non-specific volume request (or
possibly to a specific volume request). A scratch data set
would be placed on a public volume.
A storage volume
is allocated primarily to a non-temporary non-specific volume
request. (A temporary non-specific volume request may also be
allocated to a storage volume. A storage volume can also be
allocated to a specific volume request.)
A storage volume is
required by the SAVE subcommand of EDIT for a newly created data
