IBM PowerVM

A user is required for the operation of the BVQ PowerVM Scanner who should at least have read-only (hmcviewer) access to the HMC.

Please create this user before configuring the BVQ Scanner. We recommend to name the user "bvq"

Please open the user properties dialogue and select "Allow remote access via the web"

Enable performance data collection

BVQ can only collect performance statistics if "Data Collection" is enabled on the managed systems and all LPARs.

Adjust System settings

Enable "Performance Monitoring Data Collection for Managed Servers"

To lower the system load and storage capacity usage on the HMC, we recommend to reduce the number of days to store performance data below the title "Performance Data Storage" to its minimum value of "1". BVQ takes over the role to store a longer history of that data.

Adjust LPAR settings

Switch on "Enable Performance Information Collection" on all LPARs

You can check the state of the "Performance Collection" enablement per LPAR easily. Run the following script on the HMC to show all LPARs without enabled collection:

bvq@hmc3:~> for SYS in $(lssyscfg -r sys -F name); do lssyscfg -r lpar -m $SYS -F name,allow_perf_collection ; done | grep ",0"
rju_viot,0
IOS74DHP,0
HABS74D,0
HAQS74D,0
HAMS74D,0

BVQ Scanner configuration

To configure a PowerVM scanner in BVQ the following information is required:

• IP address or hostname of the HMC

• User and password of the HMC user for BVQ

Starting with BVQ 2023.H1: Redundant HMCs managing the same systems must be configured in the same PowerVM scanner. Otherwise, the managed systems will appear twice in BVQ. Define the most powerful HMC first, because the order of HMCs determines the order in which they are scanned by BVQ. Additional HMCs managing other systems should be configured in an additional PowerVM scanner.

Up to BVQ 2022.H2: Typically, two redundant HMCs manage the same IBM Power systems. Please ensure that only one scanner is created for one of the HMCs to avoid duplication in BVQ.
