SSIENAB Utility

Use the SSIENAB utility in a Single System Image environment to convert the server source directory minidisk from SSI Ready format to SSI Enabled, or to convert from SSI Enabled back to SSI Ready.

SSIENAB {ON | OFF} filemode

Definitions

ON

Converts from SSI Ready format to SSI Enabled.

OFF

Converts from SSI Enabled format to SSI Ready.

filemode

Identifies the minidisk file mode where the source directory minidisk (usually 01B0) is accessed.

Description

When SSIENAB is executed with the ON parameter, it retrieves the SSI member name from the running VM system and converts all BUILD statements in every directory entry, from the form “BUILD ON *” to the form “BUILD ON membername.”

When SSIENAB is executed with the OFF parameter, it retrieves the SSI member name from the running VM system and converts all BUILD statements in every directory entry, from the form “BUILD ON membername*” to the form “BUILD ON *.” SSIENAB can successfully convert from SSI Enabled to SSI Ready only when every BUILD statement in the directory references the same member name. The procedure to convert an SSI complex to a non-=SSI environment is to first remove all members from the system except one, then convert the single node SSI complex to a non-SSI system.

Note: For more information on using SSIENAB see “Converting non-SSI to SSI” in the Administration Guide.
