HPE InfoSight is a cloud based IT operations management platform which uses artificial intelligence (AI) for data/metric analysis. So it is able to proactively find issues in individual environments before they actually causes a problem. Currently it is possible to connect these HPE products to InfoSight: Nimble Storage, 3PAR/Primera Storage, SimpliVity HCI, Servers. This post shows how to add HPE servers to InfoSight. For this, […]
Get HPE Primera/3PAR metrics in vROPs 8.x
This post is about two cool and powerful products: VMware vRealize Operations Manger (vROPs) and HPE Primers/3PAR and how to combine them. This post includes current versions of both. Good and a bad news about costs: Bad first: vROPs free for a short period of time as trial. Good one: HPE Plug-In is free! Version 3.7 of HPE Storage Plug-ins for VMware is the first […]
Intel CIM error after update/upgrade ESXi host
It is not uncommon to get errors after a host update/upgrade you didn’t see before on the host. The following error could be seen as an example of errors with the same cause. The error I did an upgrade of a 6.5 host (installed with HPE ESXi image almost 2 years ago) to the latest HPE ESXi image of 6.7 U3. After final boot the […]
vCenter Tag based VM placement
Introduction The idea behind tag based placement is quite simple. It assists administrators to keep VMs respectively VMDKs on desired datastores, based on tags. For example, a VM is defined to be located in datacenter 1 (DC1). With tag based placement you assign tag “Storage DC1” to all datastores in DC1 and configure a policy that is assigned to VMs in DC1. All wizards in […]
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)
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 […]
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.
Ramdisk full errors
These days I had a problem with full ESXi ramdisk. Running vdf -h shows tmp as 100% used. Furthermore there are a lot of errors in vmkernel.log like: VisorFSRam: 233: Cannot extend visorfs file /var/lib/vmware/hostd/journal/ because its ramdisk (root) is full. There are some other problems these hosts suffer from time to time: vSphere HA issus like master of cluster cannot be found/elected. Connection problems with […]
3PAR – no connection to quorum witness
Recently I had problems to connect a 3PAR system to a quorum appliance. Quorum is needed in a Peer Persistence configuration. The system had a connection to the quorum. After HPE support did replace a node, connection could not be established any more. Command showcropy -qw shows error “below min safe num QAs” and other errors talking about QAs. In SSMC quorum was stated as […]
Add iSCSI targets and set target parameter with PowerCLI
The code snippet in this blog post is an example of how to add iSCSI targets to an ESXi iSCSI initiator. But there is also a loop within processing a host, that sets iSCSI target parameter. For example this can be used when a storage vendor recommends to disable delayed acknowledgment per iSCSI target, like HPE does for 3PAR and LeftHand. Here you can see […]
