HMC responding slowly to REST API calls Typically, REST API calls to the HMC should be answered within ms up to a few seconds (depending on the amount of data that is requested by the command). If the execution of those calls takes much longer resulting in unacceptably increasing performance scan durations, the problem might be caused by a bug in the IBM HMC. | No Format |

2023-06-30T12:07:51,354 INFO [performance-scan_Worker-7]: Execution of command [ScanPowerVmPerformanceData] took [1204342]ms [HMC_xxx] [PerfScan] (RawCommandExecutorImpl) |
BVQ Version: any Suggested Action: Upgrade the HMC to V10R2M1040 + iFix MF71107 or V10R2M1041 or higher. Important: Upgrading to this level will only resolve the issue if performance collection on the HMC was disabled prior to the upgrade. Otherwise one of the following two methods is required: - Reinstall the HMC
- Request the pesh password from IBM and reset Postgres DB on the HMC. All prior collected performance stats will be deleted by this reset procedure. Note: An IBM maintenance contract is required to get the pesh password:

### Postgres DB reset after V10R2M1031 installation
# Just for a better feeling ;-)
hmcshutdown -t now -r
# As hscroot, if possible save PCM data
saveupgdata -r disksftp -h <IP> -u <USER> -d <Directory> -i perfmon[,netcfg] --migrate
# As hscpe
pesh <HMC_Serial>
and then enter the "password of the day"
su -
#Insert root password, you can change it before, as hscroot do a chhmcusr -u root -t passwd
# yes twice! This resets the postgres DB - all PCM data will be lost

BVQ Version: 2021.H1.3 and above Suggested Action: The Postgres DB on VIO servers which the HMC queries to get various system information (like virtual networks, virtual storage, etc.) is broken or Postgres service (vio daemon) is not running. This causes HTTP-500 error messages on both, the HMC and BVQ scanner. The issue can be fixed using the following commands on the VIOS: | No Format |
|---|
ssh padmin@${vios}
$ oem_setup_env
# stopsrc -s vio_daemon
# /usr/sbin/slibclean
# rm -rf /home/ios/CM
# startsrc -s vio_daemon -a '-d 4' |

BVQ Version: 2021.H1.3 and above Suggested Action: Different problems can result in this error. One reason might be a full filesystem (as the error message itself suggests). Another reason might be a dodgy SEA adapter. Please run command | No Format |
|---|
entstat -all entX |
to see if there are Limbo Packets which indicate that the SEA has detected its physical network is not operational.

BVQ Version: 2021.H1.3 and above Suggested Action: Information provided by AIX and sent via REST do not match (In this case it was an hdisk which looked fine from AIX point of view but reported no location code when queried via REST API). Root cause is not understood but rebooting the VIOS servers - one after the other - probably fixes the issue.
