Disk Space Requirements for an Update
To ensure a successful update to HP-UX 11i v2, make sure that you have
at least as much disk space allocated to the file partitions listed in
Table 2-1 on page 34, and that each partition (most importantly,
/usr,/opt, and /var) has at least 10-20 percent free space to allow for
any growth. Additionally, make sure that you have at least 1 GB
allocated for /swap.
