Hello,
I need explanations about physical disks and physical volumes. What is the difference between these 2 things?
In fact, i am trying to understand what the AIX lspv2command does.
Thank you in advance. (2 Replies)
Hi All,
I have a pair of sun ultra 5_10 with SunOS 5.5.1.

I was in smit, checking on disc space, etc. and it appears that one of our physical volumes that is part of a large volume group, has no free physical partitions. The server is running AIX 5.1. What would be the advisable step to take in this instance? (9 Replies)

Hi,
I am new to unix. I am working on Red Hat Linux and side by side on AIX also. After reading the concepts of Storage, I am now really confused regarding the terminologies
1)Physical Volume
2)Volume Group
3)Logical Volume
4)Physical Partition
Please help me to understand these concepts. (6 Replies)
Hi,
When I run the free command on solaris, I get the following:
"Memory: 60G phys mem, 69G free mem"
Q: how cna the free mem be higher then the physical mem?:confused:

rcapadm
rcapadm(1M) System Administration Commands rcapadm(1M)NAME
rcapadm - configure resource capping daemon
SYNOPSIS
rcapadm
rcapadm [ [-n] -E | -D] [ -i interval=value,...,interval=value] [-c percent]
DESCRIPTION
The rcapadm command allows a user with the privileges described below to configure various attributes of the resource capping daemon. If
used without arguments, rcapadm displays the current status of the resource capping daemon if it has been configured. See rcapd(1M) for
more information.
In the current release of the Solaris operating environment, rcapadm is available to users with all privileges and to users who have the
Process Management profile in their list of profiles. The System Administrator role includes the Process Management profile.
OPTIONS -n
Do not affect the running state of the resource capping daemon when enabling or disabling it.
-E
Enable the resource capping daemon so that it will be started each time the system is booted. Also start the resource capping daemon
now, if the -n option is not specified and it is not currently running.
-D
Disable the resource capping daemon so that it will not be started when the system is booted. Also stop the resource capping daemon
now, if the -n option is not specified and it is currently running.
-i interval=value,...,interval=value
Set intervals for various periodic operations performed by rcapd. All intervals are specified in seconds. You can set the following
intervals:
scan
The interval at which rcapd scans for new processes. The default scan interval is every 15 seconds. The minimum value is 1 second.
sample
The interval of process resident set size sampling. The default sample interval is every 5 seconds. The minimum value is 1 second.
report
The interval at which various paging statistics are updated by rcapd, in seconds. These statistics can be viewed by using rcap-
stat(1SRM). The default reporting interval is every 5 seconds. When the interval is set to 0, statistics will not be updated.
Note - Paging refers to the act of relocating portions of memory, called pages, to or from physical memory. rcapd pages out the
most infrequently used pages.
config
The reconfiguration interval, in seconds. At each reconfiguration event, rcapd checks its configuration file for updates, and scans
the project databases for new project caps. The default reconfiguration interval is every 60 seconds. The minimum interval is 0.
When the interval is set to 0, no periodic reconfiguration occurs, although the running daemon can still be reconfigured by sending
it SIGHUP.
-c percent
Set the minimum physical memory utilization for memory cap enforcement. Caps will not be enforced until the physical memory available
to processes is low. The percent value should be in the range 0 to 100. The minimum (and default) value is 0, which means that memory
caps are always enforced.
EXAMPLES
Example 1: Configuring the Resource Capping Daemon with Immediate Enforcement
# rcapadm -E -i scan=15,sample=5,report=5,config=60 -c 0
EXIT STATUS
The following exit values are returned:
0 Successful completion. The modifications to the current configuration were valid and made successfully.
1 An error occurred. A fatal error occurred either in obtaining or modifying the resource capping configuration.
2 Invalid command-line options were specified.
