To import OVPA data from a node into the Capacity
Advisor database, follow these steps:
Extract OVPA data from OVPA records
Convert the OVPA data to Capacity Advisor’s
file format as a workload file
Import the workload file into the Capacity Advisor
database
Section 2.1 describes how to import OVPA data
from non-VSE systems that are not listed in the Virtualization Manager
screen but are listed on HP-SIM managed nodes. Section 2.2 describes
how to import OVPA data from systems without a ssh connection.
To import OVPA data from VSEMgr nodes, see the
capovpaextract manpage.
2.1 Importing OVPA data from HP-SIM nodes |
 |
This section presents the process for importing
OVPA data when the target system is listed in HP-SIM but not in VSEMgr.
This process requires that:
The system is a HP-SIM
node and is not listed in VSEMgr
A ssh connection is enabled
for the given system. ssh is required to execute the capovpaextract
command on the CMS.
If the above requirements are met, the user can
proceed to import data, running the capovpaextract command on the
CMS. For example, execute the following command:
capovpaextract -p HOSTNAME
where HOSTNAME is the name
of the HP-SIM node. Note that the –p option is required for
systems not listed in VSEMgr. Refer to the capovpaextract (1M) manpage
for more information and CLI options.
If the capovpaextract command completes successfully,
the OVPA data is stored in the Capacity Advisor database as a non-VSE
workload. The workload name is HOSTNAME and
can be listed using the capprofile (1M) command. To see this workload
in the VSEMgr GUI, see Section 4.
2.2 Importing OVPA Data from Systems without ssh |
|
This section describes a process for importing
OVPA data from a system without ssh access. While ssh is widely used,
sometimes it is not available, for example when the target host is
behind a firewall or the system administrator does not want to enable
direct root access to the host using ssh.
The importing process described in this section
assumes the following:
Root access on the managed
node running OVPA
A mechanism for transferring
files between the CMS and the managed node such as ftp
To import OVPA data in this case, use the following
steps:
Copy /opt/vse/lbin/extracttool
and /opt/vse/lbin/capovpaextract files from the CMS to the managed
node, assuming that VSE is installed in the /opt directory on the
CMS.
As the root user on the
managed node, set execute permissions on the scripts, using the chmod
(1) command. For example,
chmod
700 /opt/vse/lbin/extracttool /opt/vse/lbin/capovpaextract
Verify that the directory
/var/opt/mx/data/ exists on the OVPA host. If it does not exist, as
root user, use the following command to create it:
mkdir –p /var/opt/mx/data/
If /var/opt/mx/data/ already exists, then verify
that the following files do NOT exist in /var/opt/mx/data/:
| HOSTNAME.sysConfig.dat |
| HOSTNAME.sysGlobal.dat |
| HOSTNAME.sysDisk.dat |
| HOSTNAME.sysNet.dat |
| HOSTNAME.miss |
where HOSTNAME is the name of the managed node running
OVPA.As root user on the managed
node, cd to the directory where you copied the files in Step 1 and
execute the following commands:
./extracttool –f –b FIRST –e LAST
cp .capextractdir/sysConfig.dat /var/opt/mx/data/HOSTNAME.sysConfig.dat
cp .capextractdir/sysGlobal.dat /var/opt/mx/data/HOSTNAME.sysGlobal.dat
cp .capextractdir/sysDisk.dat /var/opt/mx/data/HOSTNAME.sysDisk.dat
cp .capextractdir/sysNet.dat /var/opt/mx/data/HOSTNAME.sysNet.dat
cp .capextractdir/missingData /var/opt/mx/data/HOSTNAME.miss
rm –rf .capextractdir/
|
These commands create
utilization data files in a human-readable format. The capextractdir/missingData
file is created only under certain conditions; skip the step of copying
this file if it was not generated.
Generate the Capacity
Advisor workload file by running one, not both, of the following commands:
If /var/opt/mx/data/HOSTNAME.miss is present, use the following command:
./capovpaextract -d HOSTNAME –m /var/opt/mx/data/HOSTNAME.miss -f HOSTNAME.csv
Otherwise, use the following command:
./capovpaextract -d HOSTNAME -f HOSTNAME.csv
(The file extension .csv specifies a file containing
comma-separated values.)
Use the rm (1) command
to remove the following files from the /var/opt/mx/data/ directory:
| HOSTNAME.sysConfig.dat |
| HOSTNAME.sysGlobal.dat |
| HOSTNAME.sysDisk.dat |
| HOSTNAME.sysNet.dat |
| HOSTNAME.miss |
Copy the file HOSTNAME.csv generated on the OVPA host back to the CMS,
where HOSTNAME is the name of the managed node.
On the CMS host, import
OVPA data into Capacity Advisor as an authorized user using the capprofile
command. For example,
capprofile
–i –o –S –p HOSTNAME < HOSTNAME.csv
where HOSTNAME is the
name of the managed node. This stores the OVPA data in the Capacity
Advisor database as a non-VSE workload with a workload name of HOSTNAME that can be listed with the capprofile (1M)
command.
