Issues Fixed in System Firmware 7.1.7.f or Later (Continued)

CR ID Description
6582340 When you are connected to the virtual console and
you enter the escape character sequence (#.) to enter
the SP CLI, the following two error messages might
display before reaching the CLI prompt:
read: Connection reset by peer
Write to vbsc: Illegal seek
This situation occurs when there is a lot of output
through the console, and implies that the console is in
use when it is not.
A Logical Domain May Hang When Reassigning I/O Branches
From the Control Domain to a Guest Domain (CR 6731227)
This issue is resolved by updating the system firmware to 7.1.7.f or later.
Two circumstances can cause a logical domain to hang when reassigning I/O branches from
the primary domain (control domain) to a guest domain (I/O domain):
Case 1
■
If you remove an I/O branch from the logical domain configuration of the primary domain
and then add the same I/O branch back to the primary domain, upon reboot the system might
come back up without any I/O, the system might hang in OpenBoot, or the entire I/O branch
and the associated I/O devices might be absent from the primary domain.
For example, the following actions performed in the sequence shown might lead to the
primary domain hanging in OpenBoot:
1. ldm rm-io pci@500 primary (Remove pci@500 from the configuration)
2. ldm rm-io pci@600 primary (Remove pci@600 from the configuration)
3. ldm add-io pci@500 primary (Add pci@500 back to the configuration)
4. ldm add-config config_name (Save new configuration to SP)
5. clean shutdown and power cycle
Case 2
■
If the you assign I/O branches to guest domains in any order except in numerical order, one
or more of the guest domains will be unable to start.
For example, the following actions performed in the sequence shown might lead to one or
more guest domains hanging when they are started:
Workaround
Note - Fixed in System Firmware 7.1.7.f or later.
If you are refused write access when you initiate a
connection to the host with the console command,
enter console -f (the force option) to get read and
write access.
