"Theoretically" you could have more than 120 LDOMs (as your server has 128 processor threads), but performance on each of them would be very low.

Hi !
I've been given a T5240 with 4 disks and 2 HBA cards (but no array connected). I did a factory reset on SP and NVRAM clean on OBP because the server had been used before.
I boot cdrom in single mode and try to create a hw mirror with disks from c1... but only c2 is seen by raidctl.

Hi Folks,
Just a quick question - hopefully!
I have an application currently running on a V890 with Solaris 9, I'd like to move this to either one of our T-5's or one of the T5240's in a Legacy container on an LDOM - but the fly in the ointment is the application still uses a standard Hayes... (3 Replies)

runon(1) General Commands Manual runon(1)
NAME
runon - Runs a command on a specific CPU or processor set
SYNOPSIS
runon cpu_num command [argument...]
runon -p [-x] pset_id command [argument...]
runon -r rad_id command [argument...]
DESCRIPTION
The runon utility runs the specified command (command) on the specified CPU (cpu_num), Processor Set (pset) or Resource Affinity Domain
(RAD). The argument variable specifies any options or arguments for the specified command. All the threads created by the command inherit
the CPU binding to the specified CPU (cpu_num), including threads created as the result of a fork.
If the -p option is used, the specified command is bound to a processor set rather than to a specific processor. Because a processor set
can contain more than one processor, the -p option is useful for multi-threaded applications. In addition, you can use the -x option to
specify exclusive access to a processor set.
OPTIONS
Binds to a processor set instead of a processor. You must specify the processor set identification number (pset_id), which is a unique
integer that identifies the processor set and is returned by the pset_create command.
You can specify the -x option with the -p option. Invokes Resource Affinity Domain (RAD) binding, which binds the command to a RAD
identifier (rad_id) instead of an individual processor or pset. The RAD structure holds data associated with a NUMA building block.
In this release, and for the purpose of using the runon command, a RAD is analogous to a hardware Quad Building Block or QBB. The
hardware QBB identifier also identifies the RAD. However, in future releases a RAD will be defined as a related set of memory, pro-
cessors, and I/O that might not map to a discrete QBB. Specifies exclusive use of a processor set. Use the -x option only with the
-p option.
