5 Essential Tips for Maximizing Your Experience at Nutanix .NEXT for Bloggers
I just had a security scan done against my cluster running AOS 5.5.6 and the only 'high' risk that came back was with cve-id CVE-1999-0548 (NFS Server Without Shares Detected): Description; A superfluous NFS server that is not sharing any file systems has been detected. How to Fix; Disable the NFS server. Obliviously, I don't think I want to disable the NFS server service on all of my cvm's - is there any official documentation that I can share with my peers to support this so that I can get an exemption from this risk on these systems?
I just deployed Prism central scale out on my ESXi cluster and see that the two additional PC appliances have an iso mounted to their CDROM drives. Does this need to stay connected? I’d like to spread these 3 appliances across different datastores. (And ideally, I’d like to move these across sites but I understand that this is a future feature: https://next.nutanix.com/product-ideas-61/multi-cluster-scale-out-prism-central-28305)
I just upgraded our Prism Central to version 5.7.1 and noticed that the widget with the banana-holding monkey never changes when we get an alert from one of our managed clusters. I removed and re-added the widget from the PC console but it still never updates when we receive an new alert. Grated, this is not very important but has anyone else seen this issue?
Is there an option to Pin to SSD in AOS v4.7 with vSphere hypervisor?
As a pre-step to a planned failover, I want to take a snapshot of each of my Metro PD's (4 total). Together, they are over 5 TB in used storage. Since they're all in the same Storage Pool I plan on doing one at a time so as to not compound the i/o load - does this make sense? Also, can anyone provide a *rough* estimate of how long a PD snapshot should take to complete? Thanks!
This is very minor but I wanted to get it out there. I'm running PrismCentral 4.7.3.3 to manage 6 clusters - each of those other 6 clusters are at AOS 4.7.3.1 however, in PrismCentral, under 'Explore', 'Clusters', the AOS version is still showing as the original version. It's been several weeks like this now (see below). Interestingly, when I select any of those clusters in PrismCentral, the version is shown accurately;
My cluster was looking very nice in Prism (as usual) yesterday but I happened to take a look at my NCC summary output and found that Genesis wasn't running on one of my cvm's. I was able to issue a 'genesis start' command and all was good again but I'm kind of curious if I should expect the Genesis service status to be reported up to Prism. I gather that, without Genesis running, the cvm won't play in any of the cluster reindeer games so its running status seem kind of important to me. Am I wrong in this assumption? And if not, is there some way that I can get an alarm should this happen again (other than running/reviewing NCC)? Thanks in advance.
I'm running NOS 4.7.1 with vSphere 6.0 and loving the seemless vm migration to the remote site using Metro (for a planned outage). Is there a way to perform a failback just as seemlessly - no downtime? After reading through Mike McGhee's v2.0 Best Practices document I wasn't able to find if this is possible or not.
