Upgrade Guidelines

Before upgrading StorNext, review the following upgrade guidelines:

•The trashcan feature has been removed in StorNext 3.0. Before upgrading to StorNext 3.0, you must empty the trashcan on all file systems where this feature is enabled. If the trashcan directories are not removed, the upgrade will fail.

To empty the trashcan on a file system where it is enabled, change to the file system directory (for example /stornext/snfs1). Then, at the command prompt, type:

rm -rf TrashCan

Repeat this procedure for all file systems.

•Before upgrading, make sure there is no I/O activity. On the StorNext home page, the number of store candidates should be 0. For tape drives, make sure no media is mounted and no read/write operations are being performed. If there is I/O activity, wait for the I/O activity to complete before upgrading. If you attempt to perform an upgrade during a period of high activity, the upgrade may fail.
