comment On a VM, do logical vs physical disks still matter?
Thanks for responding! I'm interested in the language to explain it. The issue is my brother's host is telling him they won't put it on separate disks because it "makes no difference in a VM". So I guess I'm wondering, would using separate VMDKs always guarantee some better performance, or no?

comment What is wrong with my logstash configuration?
@GregL these are great tips, thank you! I'll try them ASAP. Unfortunately moving the log file / copying them isn't really possible here -- this didn't strike me as non-ideal so I'll dig into logstash more to find out why it's not s good practice.

comment What is wrong with my logstash configuration?
@GregL and I did -- for the first type (ETL). Nothing came through for the second type, despite them going to the same index.

comment What is wrong with my logstash configuration?
@GregL the LogStash console output just says "Logstash startup completed." An update: the first set of files (the ETL logs) completed, but the second set (the processor logs) do not appear to have been completed. I don't see any additional logs in the logstash directory. The ES log mentions updating mappings for type ETL, but nothing for processor..

comment Server 2012: how to plan for storage failover?
It's my understanding that by using a CSV as part of scale out file server, you're writing and reading to both SANs at the same time, and thus if one SAN goes down, it shouldn't matter because the CSV can still read and write data to the remaining san. So rather than using SAN replication, the OS is what's replicating the data across both SANs. I may not have it right but that's what I'm seeking to validate.

comment Server 2012: how to plan for storage failover?
no; my entire endeavor is to avoid that. My understanding is that with SMB 3 + Mulipath I/O + CSVs, I can use 2 LUNs on my two different EMC devices to create a CSV. The CSV should leverage SMB 3.0 transparent failover. See channel9.msdn.com/Events/IT-Camps/…

comment Permissions Issue? Putty + Plink + Pageant + Powershell + Scheduled Task
I believe you're correct. the -batch command also later allowed me to prove that my service account hadn't cached the key yet (which I did fix with PsExec). Thank you!

Interestingly enough, adding the -batch argument appeared to do better than tell me why it failed -- it actually appears to have made it start working! I see the output I expect to see in the log file. After some more testing I'm going to confirm this as the answer.

comment Permissions Issue? Putty + Plink + Pageant + Powershell + Scheduled Task
Hi arober, thanks for responding. using -v -i -noageant and a passwordless private key produced same results -- works perfectly from the console, works perfectly from command prompt calling powershell.exe C:\Path\To\Script.ps1 -- and hangs from a scheduled task. I don't see any output in the event log even with the -v flag.

comment powershell call operator with multiple arguments?
Interestingly enough, that didn't fix it, but writing out the entire string does...from the command line. See my answer. It works for the console, and when I call powershell.exe C:\Scripts\script.ps1 but doesn't work from a scheduled task (which I think is a separate problem)

Ahh, a GREAT point. I added the host key as my user account but it wouldn't have been added as the server account. I'll use PsExec to run the command prompt as my service account and add the host key that way to ensure it's not the issue. I'll report back; thanks for the tip

comment Can I schedule machine boot via Dell iDRAC?
This does appear to be the case. I found an internal cloud datacenter to throw a management VM on and am using an SSH script on this to remote into the idrac and use racadm to send a powerup command to the server. It's working perfectly manually; working on the scheduled task aspect of it now. Thanks for the straightforward answer! This did end up being the way to go.

comment Can I schedule machine boot via Dell iDRAC?
I should clarify: Not worried about OOB on the DRAC -- looking to use the DRAC connection to power up the box itself in a scheduled manner. We are powering them off ahead of time and I do know when I want them to come up, but I won't be there, hence trying to schedule them to come up in the easiest way possible.

comment Can I schedule machine boot via Dell iDRAC?
thanks for the response. 1) I'm referring to turning the machine on via an idrac which will come up automatically when the machine regains power. 2) thanks, i'll probably have to script it 3) we have many buildings/datacenters; only one is going down 4) I know how to do it manually, I'm looking to script it so I don't have to get up at 3am :) 4) that's the direction I'm going I think. Thanks!

comment Powershell VMWare Script not running from Scheduled Task
I believe this highlights the issue indeed. I was attempting to call the script directly from the .ps1 extension, which this answer helped reveal as a bad idea. Calling powershell.exe from cmd with the files worked perfectly. Thank you!

comment What is the correct way to remediate an HA Cluster?
Right... in my case, I'm wondering if I can vmotion them to a specific host within the cluster so that it wouldn't be affected by a failover scenario, or if I need to vmotion them out of the cluster entirely

comment What is the correct way to remediate an HA Cluster?
@ewwhite, We're on ESXi 5.1 -- have 2 standalone hosts and two in the HA cluster. We have an older academic license on the standalone hosts and an Enteprise license on the HA cluster hosts (can do storage vMotion, etc.)

comment What is the correct way to remediate an HA Cluster?
Thanks, both of you. If I have two hosts in an HA configuration of say, server 1 and 2, can I manually force the VMs to migrate to server 2 and then take down server 1 for maintenance, or will this still cause the VMs to enter a failover scenario? Wondering if I can migrate to a specific host within a cluster or whether I'd have to migrate them onto a host outside of the cluster, essentially.
