We had to replace a hard drive in one of our Sun Blade 150s, but now it hangs during the Jumpstart. It will show 1 or 2 Timeout for ARP/RARP messages and then start the spinning numbers. It always stops at 2ae00 and just hangs there.
We have 1 combined jumpstart server and it is also our NIS+... (5 Replies)
Hi,
I have a brand new SUN T5140 machine. I am trying to install Solaris 10 on the box. When I go to the machine using a KVM session I can see a blank screen , how can I get to the OK prompt to start the installation.
Thanks,

Hi all,
I have just replaced the HDD on a Ultra 5 Spark machine, now I need to reinstall Solaris 9.
The problem is: how do I get to the OK prompt without a Sun keyboard in order to boot from CD?
At moment when I power on the machine I get the following error:

Hi Guys,
I have a small problem with a v445 which I have been informed will only boot with the reconfigure option enabled.
It is attached to HP SAN storage using qla2300 FCA's with a Veritas encapsulated rootvoldg (No Laughing here please) when I try a reboot I get the following error.

Hello,
I'm quite new to Unix but I've got an old Sun v445 server that was previously used as a backup database server, these have since been moved to new hardware. The old admin who configured the box has since retired and left no notes about it, so i have no idea what the root password is and... (2 Replies)
I have a SunFire V445 running Solaris 10 and am adding a Sun DLT tape drive. From the OK prompt the probe-scsi-all does see the drive and it is the proper target of 4. When I do the boot -- -r it does build the /dev/rmt directories correctly and the links to /devices appear correct as well. When I... (8 Replies)

chcpu
CHCPU(8) System Administration CHCPU(8)NAME
chcpu - configure CPUs
SYNOPSIS
chcpu -c|-d|-e|-g cpu-list
chcpu -p mode
chcpu -r|-h|-V
DESCRIPTION
chcpu can modify the state of CPUs. It can enable or disable CPUs, scan for new CPUs, change the CPU dispatching mode of the underlying
hypervisor, and request CPUs from the hypervisor (configure) or return CPUs to the hypervisor (deconfigure).
Some options have a cpu-list argument. Use this argument to specify a comma-separated list of CPUs. The list can contain individual CPU
addresses or ranges of addresses. For example, 0,5,7,9-11 makes the command applicable to the CPUs with the addresses 0, 5, 7, 9, 10, and
11.
OPTIONS -c, --configure cpu-list
Configure the specified CPUs. Configuring a CPU means that the hypervisor takes a CPU from the CPU pool and assigns it to the vir-
tual hardware on which your kernel runs.
-d, --disable cpu-list
Disable the specified CPUs. Disabling a CPU means that the kernel sets it offline.
-e, --enable cpu-list
Enable the specified CPUs. Enabling a CPU means that the kernel sets it online. A CPU must be configured, see -c, before it can be
enabled.
-g, --deconfigure cpu-list
Deconfigure the specified CPUs. Deconfiguring a CPU means that the hypervisor removes the CPU from the virtual hardware on which
the Linux instance runs and returns it to the CPU pool. A CPU must be offline, see -d, before it can be deconfigured.
-p, --dispatch mode
Set the CPU dispatching mode (polarization). This option has an effect only if your hardware architecture and hypervisor support
CPU polarization. Available modes are:
horizontal The workload is spread across all available CPUs.
vertical The workload is concentrated on few CPUs.
-r, --rescan
Trigger a rescan of CPUs. After a rescan, the Linux kernel recognizes the new CPUs. Use this option on systems that do not auto-
matically detect newly attached CPUs.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.
RETURN CODES
chcpu has the following return codes:
0 success
1 failure
64 partial success
