Sun SPARC Enterprise M8000/M9000 Servers Product Notes 5
General Functionality Issues and Limitations
Caution – For dynamic reconfiguration (DR) and hot-plug issues, see “Solaris OS
Issues and Workarounds” on page 8.
Note – For power-on after power-off, wait at least 30 seconds before turning the
system power back on, by using the main line switch or the circuit breakers on the
distribution panel.
■ DR and XSCF failover are not compatible. Do not start an XSCF failover while a
DR operation is running. Wait for a DR operation to finish before starting the
failover. If you start the failover first, wait for the failover to finish before starting
the DR operation.
■ For 1027A-Z/X1027A-Z, PCIe Dual 10 Gigabit Ethernet Fiber XFP cards, these
limits apply:
■ Do not use more than two cards per domain.
■ Do not use these cards in an External I/O Expansion Unit.
■ For 4447A-Z/X4447A-Z, PCIe Quad-port Gigabit Ethernet Adapter UTP cards,
these maximum limits apply:
■ No more than four cards in an External I/O Expansion Unit (two per PCIe I/O
boat).
■ No more than eight cards in a domain.
■ Do not install more than six IOUA cards per domain in a SPARC Enterprise
M8000/M9000 server if you are using a version of Solaris earlier than Solaris 10
5/08. ]
■ To complete updating the OpenBoot™ PROM firmware in the target domain, be
sure to power off/on the domain.
■ When the Solaris OS is in single user mode, do not switch from the domain
console to the XSCF Shell as the Solaris OS might switch to multi-user mode.
■ Do not use the CD-RW/DVD-RW drive unit and the TAPE drive unit at the same
time.
■ The XSCF browser interface (XSCF Web), does not support the External I/O
Expansion Unit Manager feature.
■ The use of the External I/O Expansion Unit to connect the host server to an
external boot disk drive is not supported.
■ You cannot use the following user account names, as they are reserved by the
XSCF firmware for system use: adm, admin, apache, bin, daemon, default,
ldap, nobody, ntp, operator, root, rpc, rpcuser, and sshd.
