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, […]
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 […]
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 […]
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.
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 […]
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.
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 […]
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 […]
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 […]
