STORAGEGROUP(name)

A required parameter that specifies disk related parameters for a specific Object storage group which is in the active configuration, and which was previously defined using the ISMF storage group application. This parameter on the SETDISK statement provides additional information beyond what was specified using ISMF for the Object storage group to which it pertains. For name, specify the name of an Object storage group. The disk level of the OAM storage hierarchy can only be used for the storage of the primary copy of an object, therefore an Object Backup storage group cannot be specified on the SETDISK statement.

L2TYPE

A required parameter that specifies the file system type for disk sublevel 2. There is no default value for L2TYPE. The following values, which must be specified in upper case as shown, are valid:

NFS

The file system directory to be used for this object storage group is within a Network File System (NFS).

ZFS

The file system directory to be used for this object storage group is within a z/OS File System (zFS).

Note: The hierarchical file system (HFS) is not supported by OAM.

L2DIR(location)

A required parameter that identifies the existing file system directory location within the Unix file system hierarchy to be used for this object storage group. There is no default value for location. The value for location:

• Must be from 1 to 30 characters in length
• Can contain the characters: a-z, A-Z, 0-9, '.' (period), '_' (underscore), '-' (hyphen), and '/' (forward slash)
• Is case sensitive
• Must be an absolute path beginning with / or a symbolic link. A symbolic link must resolve to a directory path with a maximum length of 100 characters
• May optionally end with a forward slash
• Is strongly recommended to be unique for each storage group to facilitate future growth and file system maintenance by identifying the location where a unique file system dedicated to the storage group has been mounted.

The existence of the location is not verified during OAM initialization. Ensure that the file system containing the specified directory is mounted before OAM processing attempts to access the file system directory location.

The following is an example of a SETDISK statement for an object storage group named SG3, which specifies that the zFS file system to be used for this storage group has been mounted in the z/OS UNIX file system hierarchy at the directory location /myoam/sg3/:

SETDISK STORAGEGROUP(SG3 L2TYPE(ZFS) L2DIR(/myoam/sg3/))
