Re: Split a string select everything after delimiter

Thank you,

 

What i am trying to accomplish is to audit a log file for anything that is an errors and find the instance of it once. I was trying the select-object -unique but since the time changes in the entries they are all different even though the error may be the same

.

 

so here is a different one and it is the complete line

 

2018-01-26T11:03:46.351Z cpu10:38380)lpfc: lpfc_scsi_cmd_iocb_cmpl:2185: 1:(0):3271: FCP cmd x1a failed <0/8> sid x011600, did x010800, oxid xffff iotag x9e2 SCSI Reservation Conflict -

2018-01-26T11:03:46.371Z cpu10:38914)lpfc: lpfc_scsi_cmd_iocb_cmpl:2185: 1:(0):3271: FCP cmd x1a failed <0/8> sid x011600, did x010800, oxid xffff iotag x114f SCSI Reservation Conflict -

2018-01-26T11:03:46.391Z cpu10:38914)lpfc: lpfc_scsi_cmd_iocb_cmpl:2185: 1:(0):3271: FCP cmd x1a failed <0/8> sid x011600, did x010800, oxid xffff iotag x997 SCSI Reservation Conflict -

2018-01-26T11:03:46.412Z cpu10:38367)lpfc: lpfc_scsi_cmd_iocb_cmpl:2185: 1:(0):3271: FCP cmd x1a failed <0/8> sid x011600, did x010800, oxid xffff iotag xc29 SCSI Reservation Conflict -

2018-01-26T11:03:46.432Z cpu10:37888)lpfc: lpfc_scsi_cmd_iocb_cmpl:2185: 1:(0):3271: FCP cmd x1a failed <0/8> sid x011600, did x010800, oxid xffff iotag xa2e SCSI Reservation Conflict -

 

 

So see how it is the same error but the time is different so i have not figured out a way to filter out all except the ones that are single instances of the error. the errors and warnings are returning different messages so ultimately i am trying to get individual errors messages for each log file so i can look at them for issues and  follow up on the ones that are real. There is a lot of data so being able to get one instance of each error or warning would be great.

 

Thanks again

vRA 7.3 - VMs with multiple IP addresses

January 26, 2018, 11:14 am

First, vRA is a pain to learn! I could go on, but here's the problem I'm having. I've setup a simple proof of concept environment, I'm trying to automate the deployment of VMs from two vCenter templates. One template exists on a single network, another on two networks. I'm able to deploy the single network template from the catalog without issue getting a correct static address from my range. The other has two static IP addresses, from two different subnets, which isn't working as expected.

 

I have two network profiles, lets called server and storage. One has a 10.x network, the other 172.x network. Each profile has a range of addresses I'm using for testing. These network profiles are linked to the Network adapter session in the Reservation.

 

The blueprint for the actual VM template is linked to a property group, which has two properties OS.VirtualMachine.Network0.ProfileName, and a second with 1 instead of 0. Each property definition has under the "Static List" section the network profile name for the "Value" field. I should now have everything linked to deploy a VM with two network adapters and get their respective IP address from the ranges setup in the network profile.

 

When my user account goes under the Catalog tab and selects Request, the next section shows the drop down boxes for choosing the networks before selecting submit. The VM gets deployed, however the addresses aren't correct. Sometimes I get two 10.x net address, two 172s, or one of each, but backwards. First time it deployed correctly oddly enough. But the address doesn't seem to get applied to the right adapter. Any ideas on how to get the addresses assigned correctly?

 

Also, since our DNS is external, the addresses and hostnames have been pre-staged. I'd need to somehow say "server01" always gets address 10.0.0.1, for instance. Is that possible here? And yes DHCP with DNS integration would solve this, currently working on but that's an internal non technical process.

 

Thanks for any help.

Re: IOPS consideration

Hello suhag79,

 

 

"Expected IOPS requirement from app team is 15000 IOPS for all the VMs to be hosted"

Weird - it showed as 9k IOPS a moment ago, what changed?

 

"I read that vSAN ready node HY-6 series (CISCO C240 M4SX) can provide up to 20K IOPS"

Source of where you read this please.

This would almost certainly be IOPS per node as there is no way of knowing how many hosts in a cluster - e.g. if you had 8 nodes in a cluster instead of 4, a per-cluster performance estimate would make no sense.

Do note that these 'up to' figures are usually done using the optimal configuration (e.g. more expensive/better disks, controllers etc.) unless otherwise specified (e.g. for a Ready-Node model that has no configurable options such as better disks).

This also assumes optimum workload characteristics such as IO size and usage-pattern.

Typically don't take any 'up to' performance as gospel - test the actual IOPS this cluster is capable of using a tool such as HCIBench.

 

"For example, if i have only one VM  running on vSAN  node-1, can that VM get whole ~ 20K IOPS ?"

If you have a non-striped FTT=1 Object this could at most use the IO performance of 2 nodes (as only 2 would be storing data-components), *potentially* if this was striped in such a manner across all hosts (e.g. 2x RAID0 mirrors each over 2 hosts, no witness components) this could use 4 hosts output but I don't think there is a way to force stripe-placement as such.

There are mechanisms in place to not starve other VMs of resources but if there is not a huge amount of contention, yes one VM can use a larger amount of storage resources than others.

Vsphere scheduled task notifications using multiple address is not working

I've setup a scheduled task to create a snapshot as we get a lot of requests to create them at odd times.  I figured scheduled tasks is best to get these jobs done and it was bonus to learn you can email the results out.

 

So I setup my first test and the job ran and sent out the email to myself with no issues.  I then setup tests again this time using 2 email address separated by semicolons as it specifies. This time I did not receive the email.

 

I've tested every way I could think of and it just won't send when you have multiple email addresses.

 

email1@company.com; email2@company.com  (Doesn't Work)

email1@company.com;email2@company.com  (Doesn't Work)

email1@company.com ; email2@company.com  (Doesn't Work)

 

email1@company.com  (Works)

 

As a temporary workaround I could email a group and just make sure the right people are in the group but it would be good to see if there's something else

Hi TheBobkin

 

We have checked with app team, if the IOPS would be same for development VMs and they says, it would be near to same and thats why figure got changed

 

Here is the source, where it is mention that IOPS can be up to 20 K.

 

http://partnerweb.vmware.com/programs/vsan/Virtual_SAN_Hardware_Quick_Start_Guide.pdf

 

i completely agreed on below point.

 

==========================================================

Do note that these 'up to' figures are usually done using the optimal configuration (e.g. more expensive/better disks, controllers etc.) unless otherwise specified (e.g. for a Ready-Node model that has no configurable options such as better disks).

This also assumes optimum workload characteristics such as IO size and usage-pattern.

Typically don't take any 'up to' performance as gospel - test the actual IOPS this cluster is capable of using a tool such as HCIBench.

====================================================

 

How much write IOPS would be impacted if we use 1 GB network. I know read IOPS will not rely  on back end network but i am more  worried about write IOPS if we go for 1 GB with FTT=1 ???

 

FYI - our 70% load would be read IOPS.

Re: Clean up "Other" objects?

Hello Mario,

 

 

I stand corrected, they are Proactive test Objects (other than that .vswp), I thought remembered from before that these had some specific format name after UUID-portion but I checked my notes from a previous case and their names end as yours do (referencing the hosts created on).

(BTW you left one reference in your last comment without *****)

 

As I was saying, find a friendly name and it should make more sense e.g. 'vsan-loadtest-debug' here.

Objects created during Proactive test are intended to be automatically cleaned up but there are a number of reasons why this process might fail (e.g. temporary partition of cluster or a host losing connection to vCenter briefly), all these Objects appear to be healthy so they should be easy to delete.

So, a vmdk on vSAN is just a descriptor that points to the vSAN Object (instead of pointing to a -flat.vmdk as they do on VMFS)

You should be able to remove these Objects relatively easy as they appear to be healthy via datastore browser and delete the vmdks (which *should* delete the backing vSAN Object), however if you say used 'rm' via CLI this would not remove the backing vSAN Object. You can check after if the Objects still exist of course.

I don't think removing folder that they reside in will remove backing vSAN Objects.

If the above doesn't work I can let you know a more sure-fire method of removal.

 

I can see the aa1a7259-b4f2-55c6-ecf2-246e963c74a8 namespace of some vmdk Objects, but do not see the namespace of

/vmfs/volumes/vsan:5208d5c6f81944d9-8520459c09710020/ab1a7259-3c21-e8ce-5a61-246e963e72f0/8a949a26-5e95-4ce1-b358-92ae23b138a7-dh-vhost01*****-0.vmdk

(e.g. ab1a7259-3c21-e8ce-5a61-246e963e72f0), is this accessible?

Hello suhag79,

 

 

Well that Ready-Node is specific about what disk-class are used in it so this 'up to' only relies on whether the IO and workload are perfectly suited for what vSAN is optimized for - 70/30 Read/Write is pretty typical so shouldn't see any issue with that aspect.

 

"How much write IOPS would be impacted if we use 1 GB network. I know read IOPS will not rely  on back end network but i am more  worried about write IOPS if we go for 1 GB with FTT=1 ???"

 

 

It generally matters more about the switch really - Hybrid runs fine on dedicated 1Gb uplinks so this shouldn't be a bottleneck, however there can be a HUGE difference in capabilities of a cheap 1Gb switch vs an expensive one.

Could be that I'm misunderstanding your request, but that is exactly what my earlier code is doing.

It leaves out the timestring, takes the identification of the system, and then tells how many times that messages was logged, independent of the time string.

Re: Newly deployed PSC appliance setup is stuck at 40%

Update: I went back to 6.5f before update 1. I was able to get through the complete deployment of the PSC.

What's interesting is that after it was to 50% to 60% complete on stage 2 of the configuration. A session expired popped up. I re-entered by root password and bam... It completed successfully. I'm wondering if there is some sort of session timeout issue in the Update 1 iso that isn't popping up like what happened in 6.5f iso.

 

I do have a support case open about this. Waiting to hear back.

Thanks TheBobkin,

 

Since our read IOPS work load is more than 70-80% , i think, we can go with 1 GB network.

 

Thanks again for your help.
