The Solaris 8 operating environment includes a new feature that enables you to install large partitions. The DPT PM2144UW controller's BIOS must support Logical Block Addressing (LBA). The latest revision of the BIOS fully supports LBA access. The problem can also affect other DPT controller models.
Workaround: Prior to upgrading your system to the Solaris 8 operating environment, ensure that the DPT PM2144UW controller's BIOS is the latest available version from DPT.
Run the prtconf -D.
If the name dpt is displayed, run the card's configuration utility to obtain information about the model and BIOS revision.
Upgrade DPT PM2144UW controllers by flashing the BIOS or by installing the latest BIOS EPROM obtained from DPT. See http://www.dpt.com for the latest BIOS images for all DPT controllers.
You can now upgrade the system to the Solaris 8 operating environment.
