You must remove the Tivoli® Storage Manager for Space Management
GPFS client before installing a new version. You must deactivate the Tivoli Storage Manager for Space
Management GPFS client, disable failover, and remove the Tivoli Storage Manager for Space Management
GPFS client from all nodes.
About this task
If
you want to upgrade the Tivoli Storage
Manager for Space Management client, you must uninstall and install
the backup-archive client and the API to get the product to the same
version and level. A mixed installation is not supported. Activity
on the space-managed file systems should be avoided during software
installation. Access to migrated files during the upgrade is not possible,
because the system would be suspended while trying to read a file
stub.
To upgrade the Tivoli Storage
Manager for Space Management GPFS™ client,
complete the following steps:
Procedure
- Ensure that all HSM nodes (owner and backup) are in a consistent
state and that all space-managed file systems are mounted on all HSM
nodes.
- Globally deactivate HSM on every node by issuing the command:
dsmmigfs globaldeactivate.
- Disable failover on every node by issuing the command:
dsmmigfs disablefailover.
- To figure out which node owns which
cluster file system, issue the dsmmigfs q -d command
on one of the nodes.
- Remove Tivoli Storage
Manager for Space Management from all nodes. You must not
upgrade with a command like rpm -U. You must uninstall
the old version and then install the new version.
- Install Tivoli Storage
Manager for Space Management on all nodes.
- Globally reactivate HSM on every node by issuing the command:
dsmmigfs globalreactivate.
- Enable failover on every node by issuing the command: dsmmigfs
enablefailover.
- Take over each file system on its owner
node as known from step 4. With distributed HSM, the HSM daemons also run on these nodes,
which are designated for the failover feature.
