Adjusting Required Minimum File System
Sizes
Update Requirements
The absolute minimum /usr file-system sizes needed to update to
HP-UX 11i are listed in “Disk Space and Memory Requirements” on
page 62 in Chapter 3. If the required file-system size for the bundle you
copy to a depot exceeds the file system limit set by your disk installation,
you will get an error condition during the copy process. You can use
lvextend and extendfs in this situation to create a larger file system.
You might have a problem updating your systems if any of these volumes
are too small: /usr, /opt, /stand or /var. See “Disk Space and Memory
Requirements” on page 62 in Chapter 3.
If you try an update, swinstall will determine how much disk space is
required. If sufficient space is not available, swinstall will report an
error like this:
ERROR: The used disk space on filesystem "/var" is estimated
to increase by 57977 Kbytes.
This operation will exceed the minimum free space for this
volume. You should free up at least 10854 Kbytes to avoid
installing beyond this threshold of available user disk space.
In this example, you would need to increase the file system size of /var
by 10 MB, which actually needs to be rounded up to 12 MB.
Increasing /var
Follow these steps to increase the size limit of /var:
Step 1. Determine if any space is available for the /dev/vg00:
/sbin/vgdisplay /dev/vg00
You should see output like this:
- Volume groups -
VG Name /dev/vg00
VG Write Access read/write
VG Status available
