Tivoli Space Manager for UNIX Using the Hierarchical Storage Management Clients

dsmmigfs

Valid on AIX GPFS file systems only

The dsmmigfs command used with the SDRreset, SDRupdate, enableFailover, or disabledFailover parameter manages recovery from partial system failure. One HSM client can take over from an HSM client that is involved in a partial system failure if the following conditions are true:

Syntax

>>-dsmmigfs--+- SDRupdate-------+------------------------------><
             +- SDRreset--------+
             +- enableFailover--+
             '- disableFailover-'
 
 

Parameters

SDRupdate
The dsm.opt file and the dsm.sys file are stored in the SDR. The set of two options files in the SDR become the single, shared set of options files for all HSM clients within the local GPFS node set. After you update your dsm.opt or dsm.sys file, use this command to synchronize all participating nodes within a GPFS node set.

SDRreset
Do not use this command during normal operation.

The HSM client attempts to reset potential locking problems in the SDR. If a command or a failover operation ended abnormally, this command will help to achieve a consistent system state.

enableFailover
Activates the local node for failover operations within the local GPFS node set.

disableFailover
Deactivates failover operations on the local node.

Examples

Task Command
Deactivate failover operations on the local node. dsmmigfs disableFailover
