To assign a volume to a reserve storage pool, you initialize the volume using the ICKDSF INIT
command with these parameters:
- RESERVED
- Initializes the volume as reserved, which specifies that it cannot be brought online.
- OWNERID
- Specifies the name of the reserve storage pool, in the form IBMRSPrspname where
rspname is the name of the reserved storage pool (up to 8 characters). OWNERID is
optional.
A volume that has been initialized as reserved cannot be brought online. Before it can be
brought online, it must be re-initialized without the RESERVED keyword. For more information,
refer to
INIT command in
Device Support Facilities (ICKDSF) User's Guide and Reference.
A volume that has been initialized as reserved is not to be confused
with a device for which a system issues a hardware RESERVE, either
through the RESERVE or ISGENQ macros, to ensure successful serialization
of shared DASD. For more information, refer to z/OS MVS Programming: Authorized Assembler Services Reference LLA-SDU or z/OS MVS Programming: Authorized Assembler Services Reference EDT-IXG.
