Partitioning A Usb Disk - HP FlexFabric 7900 Series Configuration Manual

Restrictions and guidelines
To mount/unmount a partitioned storage medium, you must mount/unmount all the partitions
individually, instead of mounting/unmounting the medium as a whole. To unmount a USB disk, make
sure the system has recognized the USB disk and the USB disk LED is not blinking. Otherwise, the USB
interface or USB disk might be damaged.
Before unmounting a storage medium, make sure no other users are accessing the medium. Otherwise,
the unmount operation fails.
Configuration procedure
Perform one of the following tasks in user view as appropriate:
Task
Mount a storage medium.
Unmount a storage medium.

Partitioning a USB disk

A USB disk can be divided into logical devices called "partitions." Operations on one partition do not
affect the other partitions.
The following partitioning modes are available for USB disks:
Simple—Specify the number of partitions. The system divides the USB disk into the specified
•
number of partitions with the same size.
Interactive—The system partitions the USB disk according to user input. Each partition must be at
•
least 32 MB.
Restrictions and guidelines
It is normal that the specified partition size and the actual partition size have an error less than 5% of the
total memory.
Before partitioning a USB disk:
Back up the files in the storage medium. The partition operation clears all data in the medium.
•
If you are partitioning a USB disk, make sure the disk is not write protected. Otherwise, the partition
•
operation will fail, and you must remount or reinstall the disk to restore access to the USB disk.
• Make sure no other users are accessing the medium. Otherwise, the partition operation fails.
After partitioning a USB disk:
• Reconfigure paths of application files to include the correct partition information.
To guarantee the startup system software image and configuration files sufficient storage space, set
•
the path for log files to a partition other than the first partition. By default, the system automatically
saves log files to the second partition. If the path does not exist, use the info-center logfile
switch-directory command to change the path to avoid log loss. For more information about this
command, see Network Management and Monitoring Command Reference.
