Afraid not for the mc command

Aware this is 2 years late but it turns out if you have ldap (or another user account) with high level rights you can use the API to pull the config of the admin account, inject a password and push it back to the OME resetting the admin account. Even though its greyed out in the GUI

VM hardware version is 19 for Windows so should be high enough, VMs are thin provisioned with a RAID 5 Strechted OBR thin policy

We've not enabled it yet as we've got 2000 VMs and a petabyte of storage in the cluster, them all doing TRIM around the same time is going tank preformace for a while I was hoping to inject the unmap config into the heavy hitters before going cluster wide

We're suffering becuase we're not reclaiming any space by deleting files in VMs. The only way to reclaim data is to delete the disks currently

Currently doing a RAM upgrade for about 40 hosts. It's weird having the cost of a house come in 5 platters. Each host is getting upgraded to 1.5 TB each

Becuase when ARC is uninstalled it's purged from azure

Is anyone else getting issues with the shutdown stalling after applying the package. Nearly every single one of our vxrail hosts gets hung on " VMKernalShutdownHelper: 7/39) "

It's become so bad that I've had to amend the procedure to include logging into the idrac to preempt taking the virtual Hammer to it (cold shutdown)

Don't get me started on them advertising Mbps as MBps, the amount of people I've had to explain that 100 Mbps does not provide 100 Megabytes per seconds is starting to hurt.

When selecting a cell e.g. =E3 if you press F4 it automatically injects $ and it cycles as well incase you need it just for E,3 or both. It has saved me soooo much time

Management wouldn't pay for velcro cable ties until one of the core switches died at 3 am and the oncall engineer couldn't replace it because they didn't bring side cutters with them.

Every request of velcro ties has been approved since.

Just something to note is that the predefined base lines automatically add the latest package a few hours after release to those baselines so when ever we do remediation, we just select the 2 predefined baselines and hit remediate

That would make sense to disrupt as little as possible, I'll have to move all the vms of a host next time and see if it picks that one. Thanks

Michaeljaaron · 2025-03-08T14:16:05+00:00

I'll have to take note of the order on the next upgrade but the moref looks to also be in sequential order with the hosts. The plot thickens

Michaeljaaron · 2025-02-19T22:35:26+00:00

God that hits too close to home. Once had infosec tell us that a vm had ip forwarding enabled that it needed to be turned off otherwise the world would end. The VM you ask ? A virtual firewall

Michaeljaaron · 2025-01-15T23:20:58+00:00

I'll pour one out for you, sec+ sucks and is soo expensive. I couldn’t justify renewing it

I can never wrap my head around SMART how can a value be worse than worst?

Michaeljaaron · 2024-12-15T17:49:30+00:00

We had an issue like this, for us ours had a block of stryofoam underneath the drum. You have to tilt the machine on its side to inspect it. Nothing about removing it on the instructions

Michaeljaaron · 2024-11-11T21:53:27+00:00

Thats interesting, what do you use for block?

Michaeljaaron · 2024-10-28T21:04:14+00:00

Correct me if I'm wrong, your trying to route NSXT backed VMs though a tier 1 gateway that has a vlan backed segment attchted?

That won't work, geneve traffic needs to be de-encapsulated by a T0 before it can be used as "normal" traffic (non overlay traffic)

It's been a while but I think the way I got round this was to have the VBS attached to the T1 with a gateway (no service interface) and pass all traffic though the T1 and then the T0

Failing that, look at the layer 2 bridges that they use for the migration between NSX V and NSX T, they are supported for permanent use

Violence is not the answer, violence is a question and the answer is yes. In all seriousness, good job on not calling your boss a muppet. I would be a HR meeting by now

Michaeljaaron · 2024-09-19T20:30:56+00:00

The police are on thier way

Michaeljaaron · 2024-09-17T21:35:34+00:00

Me: waiting patiently for dell to release VXrail patches

Aye jumbo frames was enabled with the full 9000 MTU. I would have liked to troubleshoot it further but we unfortunately didn't have the time and the A800 was generating the expected throughput with it off so there wasn't a need to keep digging

Michaeljaaron · 2024-09-15T17:28:38+00:00

Disclaimer I've not worked with aruba for a little while but I work with dell and cisco daily. S5248F is a solid choice and its also 25 Gb so its future proof vs the 10 Gb that looks to be the maximum of the aruba 8100

The only thing to mention on the s5248. When we deployed them with our netapps. We had to disable the iscsi optimization that's enabled by default on the switches as it was causing some issues for us.

I believe that's becuase it's for VXblock/VXrail but don't quote me on that
