To work around this problem, you have two main choices.
Workaround: There are two scenarios, depending on your preference.
Use the command-line installation (es-inst) for server-layer installation.
Use the GUI-based installation utility (es-guiinst) with one of these three options:
Copy both disks (CD 1 and CD 2) onto a disk drive locally as explained below.
CD 1 should be copied to target-directory/disk1 and CD 2 to target-directory/disk2.
Load CD 1 and CD 2 in different CD drives and NFS mount them so that CD 1 is mounted on the target host as mount-directory/disk1 and CD 2 is mounted as mount-directory/disk2.
Download the web image from http://www.sun.com onto a system which has the structure as specified in option 1.
After doing any of the above options, run es-guiinst from the disk1/sbin directory.
