The ordering of the drives in the list returned to the client is
based on the medium’s current physical location. Drives that
are not mounted are listed before drives that are mounted.
Consequently, for a mounted medium, the drive on which the
medium is currently mounted may not be the first drive in the
returned list.
The total length of time the API software waits for a command
status in synchronous mode from VolServ is
(VSID_RETRY_LIMIT plus 1) multiplied by
VSID_TIMEOUT_VALUE.
If the VSID_ENTERPRISE_ID parameter is set to any value
other than zero, the intermediate and final status for this request
is returned to the enterprise registered with VolServ.
When the API software is operating in asynchronous mode,
client software must call VS_Select to receive final status on
a Query Mount request submitted through the API interface to
the VolServ system.
Two levels of default parameter settings are used in the API
software—global defaults and command-specific defaults.
• Global defaults for all commands are initialized at startup
and can be set or retrieved using VS_Global_SetFields
and VS_Global_GetFields function calls.
• Command-specific parameter defaults for Query Mount
commands are set with
VSCMD_QueryMount_SetDefaults. If
