New in 3PAR SSMC 3.6: Topology Insight

New in 3PAR SSMC 3.6: Topology Insight

A new – and badly documented – feature in StoreServ Management Console 3.6 is Topology Insights. Sounds first like the probably known Maps. But Topology View shows an end-to-end view: VM <–> VMDK <–> Datastore <–> Host <–> Virtual Volume <–> System. Enriched with performance-information! This short post is about this feature and how to get it.

PSP rule for active/standby controller arrays (like Nimble Storage)

PSP rule for active/standby controller arrays (like Nimble Storage)

First, what does active/standby mean. For this blog post, it means the array hast at least 2 controllers, one presents ALL LUNs to the hosts, the second controller presents NO active LUNs path to the hosts. Just in case of a manual or automatic failover, the second controller takes-over ALL LUN-presentations – and active paths. Examples of such arrays are: [very old one] HP MSA 1000 HPE Nimble […]

VCSA 6.7 U3 sends no log data to syslog server

VCSA 6.7 U3 sends no log data to syslog server

Recently a customer noticed that all his vCenter Server Appliances (VCSA) running 6.7 U3 (6.7.0.40000 respectively 6.7 build 14368073) do not send any data to syslog server any more. Rebooting VCSA or restarting service gets the system to send data again – for a few minutes. Changing syslog-settings in Appliance Management (VAMI, Port 5480) also brings VCSA to send logs for a few minutes. VMware […]

Cannot add 3PAR storage provider because of certification error

Cannot add 3PAR storage provider because of certification error

Normally when using a self-signed certificate you get a warning. It is also normal to accept the certificate to continue your task. These days I wanted to register a 3PAR system as storage provider in vCenter. Because of a certification error, this could not be accomplished. In this post I describe how to solve – at least my – problem.

No storage snapshot in Veeam B&R after 3PAR failover

No storage snapshot in Veeam B&R after 3PAR failover

Recently I had a strange behavior when creating 3PAR snapshots in Veeam Backup&Replication after a site-failover (Peer-Persistence) occurred. Snapshot-jobs stop with error, backup-jobs using 3PAR integrated snapshots jobs are still running because they  failed over to NBD. Snapshot-jobs were configured using secondary 3PAR for snapshots too – see more information here. Management console showed the following error for snapshot-jobs: VM VM name does not meet […]

Using PowerCLI to set mail recipient for a bulk of alarms

Using PowerCLI to set mail recipient for a bulk of alarms

In this post I will describe how to use PowerCLI to add a trigger and a mail recipient to selected vSphere alarms. This is an excellent example of how PowerCLI can easily be used to do a task in a few moments while needing maybe hours when doing in GUI. A use-case for assigning a trigger and recipient to many alerts can be the implementation […]
