25.3.1 Notes on Upgrade
25.3.1.1 Supported Firmware and Software
The new CPU (the SPARC64 VII or SPARC64 VII+ processor), CMU, IOU, and IOUA
for upgrade are supported by the XCP firmware and Oracle Solaris software of a certain
version.
For the SPARC64 VII and SPARC64 VII+ processors, the XCP version to be used varies
by the CPU operating frequency.
For details on the minimum requirements of software and firmware, see the latest Product
Notes.
Prior to upgrading CPU (the SPARC64 VII or SPARC64 VII+ processor), CMU, IOU,
and IOUA on the M8000/M9000 server, complete the update of XCP firmware and Oracle
Solaris OS.
To mount a new FRU for upgrade to a domain on which the XCP version has been
updated from XCP 1070 or earlier, restart the domain to complete the OpenBoot PROM
firmware update of the target domain.
