HP e3000 MPE/iX System Software Maintenance Manual (Release C.75.00) (30216-90344)

Chapter 3
Planning for Your Task
3.6 Estimating Disk Space
70
The combined System Load Tape (SLT) and Fundamental Operating System (FOS) are the minimum
requirements for any system software version. Ensure that you have enough room on LDEV 1 for all the SLT
files. The FOS files do not have to go onto LDEV 1.
IMPORTANT Values for Express and PowerPatch 7.0 versions are given in the Read Before Installing for
each release after C.70.00.
There are several conditions under which you need additional non-contiguous disk space. Refer to the
appropriate following subsection for information on estimating non-contiguous disk space for your specific
task.
• Updating your system software.
• Adding-on new SUBSYS products to your system software.
• Applying PowerPatch to your system software.
• Applying Reactive patches to your system software.
• Distributing Staging Area to a remote system.
Disk Space Estimate for Updating
To estimate the amount of additional permanent (net) non-contiguous disk space required to update your
system software, subtract the value for your current version from the value for the version you are updating
to.
Record the disk space sectors required for the Update on your checklist.
Disk Space Estimate for Add-on
The values are listed in Table 3-1 on page 58 “Non-Contiguous Disk Space Requirements,” for the SUBSYS
(purchasable subsystem products) are the maximum for all possible purchasable products.
Estimate purchased product (SUBSYS) disk space based on the number and kind of software subsystem
products that you purchased.
If you are not adding-on any new purchased products, the disk space sectors currently being used by your
existing products will remain the same.
Record the estimated disk space required for SUBSYS products on your checklist.
