23.15 Multiple Server Activation Prevention Commands

The management file for pool MSAP is _admin\manage_nss\pool\ poolname\zlss\msap.xml . One file exists for each pool. This file contains MSAP statistics for the pool. The MSAP attribute is displayed in the enabledAttributes tag of the poolinfo.xml management file.

For manage.cmd, the pool operation getPoolInfo returns the MSAP tag ( <msap>) in the supportedAttributes tag ( <supportedAttributes>) and the enabledAttributes tag ( <enabledAttributes>).

For APIs, the pool feature zpool_feature_msap can be viewed and controlled using the zGetInfo and zModifyInfo commands.

MSAP Console Command

Description

 
nss /msapserver

Enables MSAP for all the pools on the server. By default, MSAP is enabled for every pool on the server. We recommend that you never disable MSAP. 

nss /nomsapserver

Disables MSAP for all the pools on the server. This command remains in effect only until the server is next rebooted. We recommend that you never disable MSAP.

 
nss /msaprebuild

Rebuilds a corrupt MSAP block. Before issuing the command to rebuild, you must deactivate the pool because a corrupt MSAP prevents a pool from going into Maintenance state. Rebuilding an MSAP block does not give the rebuilder ownership of the pool. 

nss /poolmsap=pool

Enables MSAP for a given pool on the server. MSAP is enabled the next time the pool is activated. (Enter the command, deactivate the pool, then activate the pool. MSAP is now enabled.)

 
nss /nopoolmsap=pool

Disables MSAP for a given pool. Use the command when the pool is activated. MSAP is disabled the next time the pool is activated. (Enter the command, deactivate the pool, then activate the pool. MSAP is now disabled.)

 
nss /pools

Displays the message “Multi-use detect” for pools that have MSAP enabled.
