ESXi stops sending syslog after uprade from 6.5 U2 to 6.7 U2.

Recently we upgraded a lot of ESXi hosts to 6.7U2. After a while I noticed that a volume of logs in our syslog server had decreased. After some investigation I discovered that after the upgrade the “syslog” rule in the ESXi firewall was no longer enabled.

By running this PowerCLI command it enabled the rule again and logs appeared in the syslog server again – Get-VMHost | Get-VMHostFirewallException | where {$_.Name.StartsWith(‘syslog’)} | Set-VMHostFirewallException -Enabled $true

HPE iLO problem with Embedded Flash/SD-CARD

Some time ago I discovered two HPE BL490c Gen9 servers with iLO in “Degraded” status. From diagnostic page it was visible that error was related with Embedded Flash/SD-CARD – “Embedded media manager failed initialization”. The Login banner was also showing a warning.

With ILO4 firmware 2.61 or newer there is a “Format” button to format the embedded Flash/SD-CARD. If you format the embedded Flash/SD-CARD the iLO will reset and and hopefully the error is fixed. It worked on one of my servers. The other one was still showing error after iLO reset. Then I performed a power-cycle to the blade server using E-FUSE process. Logged into Onboard Administrator and issued “server reset <bay_number>”. After the server re-started the error about the iLO disappeared.

VMWare virtual machine exluded from Veritas Netbackup query based policy

Recently I discovered that some of our VMs were no longer backed up by NetBackup with no obvious reason. After some investigation we discovered that all the VMs that were no longer backed up had one or more Independent Persistent hard disks configured. This alone should not be a problem NetBackup should just ignore those disks while performing a backup from the VM but we also had configured a filter in NetBackup not to include VMs with RDM ( Raw Device Mapping) – “AND NOT VMHasRDM Equal TRUE”. It seems that NetBackup considers Independent Persistent disks and RDM disks as the same. By removing the filter from the query the VMs were included in to the backup again.
