Storage Group Create Option

The Storage Group Create option performs all functions of the SQL CREATE STOGROUP statement. This statement defines a set of VSAM controlled volumes on which storage can later be allocated for tablespaces and indexes. When defining a storage group, you must enter the names of the volumes or VCATs that the storage group will reference. Selection lists can be used.

The Storage Group Create option performs all functions of the SQL CREATE STOGROUP statement. This statement defines a set of VSAM controlled volumes on which storage can later be allocated for tablespaces and indexes. When defining a storage group, you must enter the names of the volumes or VCATs that the storage group will reference. Selection lists can be used.
The Storage Group Create screen provides an easy way to supply the information that is necessary for storage group creation. For information about the fields, see the online help.
You can use the insert and delete commands to manipulate the volume entries. (Block mode is also supported.) Although move and copy are valid commands, they are irrelevant, as volume order is not important. Also, replicate is not supported, as the same volume name cannot be designated more than once. Enter an asterisk (*) to select an SMS-managed volume.
Db2 does not validate the volume names or VSAM catalog name when the storage group is created. These objects are only validated when a tablespace or index is defined that references the storage group. Therefore, when a tablespace or index that references a storage group is created with an invalid VSAM catalog name or volumes, the tablespace or index create will fail. In the case of invalid volumes, Db2 will issue a CONNECT command to the console for the missing volumes.
After creating a storage group, the Creation Confirmation screen enables users to accept, edit, or reject the DDL to be used to create the object.
