Creating a file system
About this task
File system configuration and management are out of the scope of this document.
NOTE: Some file systems may require you to properly-align the file system on the PowerStore volume. It is recommended
to use specified tools to optimally match your host with application requirements.
NOTE: Creating a file system formatting with UNMAP enabled on a host connected to PowerStore may result in an
increased amount of write I/Os to the storage subsystem. When possible, it is highly recommended to disable UNMAP
during file system creation. Disabling UNMAP can be done when using the Veritas Volume Manager on the HP-UX host.
However, when using the HP-UX native volume manager, this recommendation is not applicable as UNMAP is not supported
in this case.
To disable UNMAP during file system creation (only when using Veritas Volume Manager):
Steps
1. Access the HP-UX host using SSH as root.
2. Run the following vxdisk command to temporarily disable UNMAP for the targeted device on the host (prior to file system
creation):
# vxdisk set reclaim=off "disk name"
3. Once file system creation is complete, re-enable UNMAP for the targeted device on the host, by running the following
command:
# vxdisk reclaim "disk name"
NOTE:
To verify the current setting of a specific device using its corresponding disk group, run the following vxprint
command:
#vxprint -z -g "disk group name"
Example: Using the vxprint command to verify the current UNMAP setting of a specific device:
# vxprint -z -g testdg
