This section describes command failures.

• Manual pages not accessible with the man command. Set the MANPATH environment variable appropriately.

• The mount, fsck, and mkfs utilities reserve a shared volume. They fail on volumes that are in use. Be careful when accessing shared volumes with other utilities such as dd, it is possible for these commands to destroy data on the disk.

• Running some commands, such as vxupgrade -n 7/vol02, can generate the following error message:

  vxfs vxupgrade: ERROR: not primary in a cluster file system

  This means that you can run this command only on the primary, that is, the system that mounted this file system first.
