6.2 HP IBRIX 9300/9320 Storage Administrator Guide (AW549-96049, December 2012)

NOTE: To use the verify_client command, the 9000 client software must be installed.
Upgrading Windows 9000 clients
Complete the following steps on each client:
1. Remove the old Windows 9000 client software using the Add or Remove Programs utility in
the Control Panel.
2. Copy the Windows 9000 client MSI file for the upgrade to the machine.
3. Launch the Windows Installer and follow the instructions to complete the upgrade.
4. Register the Windows 9000 client again with the cluster and check the option to Start Service
after Registration.
5. Check Administrative Tools | Services to verify that the 9000 client service is started.
6. Launch the Windows 9000 client. On the Active Directory Settings tab, click Update to retrieve
the current Active Directory settings.
7. Mount file systems using the IBRIX Windows client GUI.
NOTE: If you are using Remote Desktop to perform an upgrade, you must log out and log back
in to see the drive mounted.
Upgrading pre-6.0 file systems for software snapshots
To support software snapshots, the inode format was changed in the IBRIX 6.0 release. The
upgrade60.sh utility upgrades a file system created on a pre-6.0 release, enabling software
snapshots to be taken on the file system.
The utility can also determine the needed conversions without actually performing the upgrade.
When using the utility, you should be aware of the following:
• The file system must be unmounted.
• Segments marked as BAD are not upgraded.
• The upgrade takes place in parallel across all file serving nodes owning segments in the file
system, with at least one thread running on each node. For a system with multiple controllers,
the utility will run a thread for each controller if possible.
• Files up to 3.8 TB in size can be upgraded. To enable snapshots on larger files, they must be
migrated after the upgrade is complete (see “Migrating large files” (page 154).
• In general, the upgrade takes approximately three hours per TB of data. The configuration of
the system can affect this number.
Running the utility
Typically, the utility is run as follows to upgrade a file system:
upgrade60.sh file system
For example, the following command performs a full upgrade on file system fs1:
upgrade60.sh fs1
Progress and status reports
The utility writes log files to the directory /usr/local/ibrix/log/upgrade60 on each node
containing segments from the file system being upgraded. Each node contains the log files for its
segments.
Log files are named <host>_<segment>_<date>_upgrade.log. For example, the following
log file is for segment ilv2 on host ib4–2:
ib4-2_ilv2_2012-03-27_11:01_upgrade.log
