Newbie & LPAR

Hello,

what is the meaning of:


Code:
lparstat -i
Node Name : ****
Partition Name : ****
Partition Number : 1
Type : Shared-SMT
Mode : Capped
Entitled Capacity : 2.00
Partition Group-ID : 32769
Shared Pool ID : 0
Online Virtual CPUs : 4
Maximum Virtual CPUs : 4
Minimum Virtual CPUs : 2
Online Memory : 16384 MB
Maximum Memory : 20480 MB
Minimum Memory : 8192 MB
Variable Capacity Weight : 0
Minimum Capacity : 1.00
Maximum Capacity : 4.00
Capacity Increment : 0.01
Maximum Physical CPUs in system : 16
Active Physical CPUs in system : 16
Active CPUs in Pool : 16
Shared Physical CPUs in system : 16
Maximum Capacity of Pool : 1600
Entitled Capacity of Pool : 1400
Unallocated Capacity : 0.00
Physical CPU Percentage : 50.00%
Unallocated Weight : 0
Desired Virtual CPUs : 4
Desired Memory : 16384 MB
Desired Variable Capacity Weight : 0
Desired Capacity : 2.00

I see 8 "CPU"(Cores) in topas. Is every topas-CPU limited to 25% of one physical core? Or if only one topas-CPU is used, could it gain 100% from one physical Core?

Thx
Talulah

Additional question:
Code:
lparstat -i: 4 Online Virtual CPUs

Why are there eight CPUs in topas?

NAME
icapd - Instant Capacity (iCAP) daemon. SYNOPSIS
icapd DESCRIPTION
The (formerly ) daemon is installed and started as part of the Instant Capacity software on all potential iCAP systems, and respawns itself if killed. If this daemon is not running, other Instant Capacity commands fail. The operations this daemon performs are vital in keeping the complexwide view of the Instant Capacity state current. The following entry is added to /etc/inittab in order to have start and respawn itself: icap:23456:respawn:/usr/lbin/icapd # Instant Capacity daemon This daemon is not started on hardware that is not supported under the Instant Capacity program. If is installed and running on a system with Instant Capacity components present (cores, cells, or memory), it sends daily asset report email to HP (if so configured), tracks tem- porary capacity, sends exception notifications, and maintains a healthy Instant Capacity state. For more information about the functions that performs for Instant Capacity systems, see the located at /usr/share/doc/icapUserGuide.pdf. The daemon reports errors via (see syslog(3C)). Exception notification email is sent to root and to the system contact email address (con- figured via the command (see icapmodify(1M)). The daemon performs periodic operations based on the time of day. The daemon is spawned by and gets its time zone specification from the /etc/default/tz file. By default, the time zone specified in /etc/default/tz is EST5EDT. You can specify which time zone the daemon uses to interpret its current time by modifying the /etc/default/tz file. For details about the time zone format, see environ(5). A restart of the daemon is required before the new time zone value takes effect (that is, kill the process). AUTHOR
