Remove the ' system VLAN "Nexus 1000V port-profile
We have a Dell M1000e blade chassis with a number of Server Blade M605 ESXi 5.0 using the Nexus 1000V for networking. We use 10 G Ethernet fabric B and C, for a total of 4 10 cards per server. We do not use the NIC 1 G on A fabric. We currently use a NIC of B and C fabrics for the traffic of the virtual machine and the other card NETWORK in each fabric for traffic management/vMotion/iSCSI VM. We currently use iSCSI EqualLogic PS6010 arrays and have two configuration of port-groups with iSCSI connections (a physical NIC vmnic3 and a vmnic5 of NIC physical).
We have added a unified EMC VNX 5300 table at our facility and we have configured three VLANs extra on our network - two for iSCSI and other for NFS configuration. We've added added vEthernet port-profiles for the VLAN of new three, but when we added the new vmk # ports on some of the ESXi servers, they couldn't ping anything. We got a deal of TAC with Cisco and it was determined that only a single port group with iSCSI connections can be bound to a physical uplink both.
We decided that we would temporarily add the VLAN again to the list of VLANS allowed on the ports of trunk of physical switch currently only used for the traffic of the VM. We need to delete the new VLAN port ethernet-profile current but facing a problem.
The Nexus 1000V current profile port that must be changed is:
The DenverMgmtSanUplinks type ethernet port profile
VMware-port group
switchport mode trunk
switchport trunk allowed vlan 2308-2306, 2311-2315
passive auto channel-group mode
no downtime
System vlan 2308-2306, 2311-2315
MGMT RISING SAN description
enabled state
We must remove the list ' system vlan "vlan 2313-2315 in order to remove them from the list" trunk switchport allowed vlan.
However, when we try to do, we get an error about the port-profile is currently in use:
vsm21a # conf t
Enter configuration commands, one per line. End with CNTL/Z.
vsm21a (config) #-port ethernet type DenverMgmtSanUplinks profile
vsm21a(config-port-Prof) # system vlan 2308-2306, 2311-2312
ERROR: Cannot delete system VLAN, port-profile in use by Po2 interface
We have 6 ESXi servers connected to this Nexus 1000V. Originally they were MEC 3-8 but apparently when we made an update of the firmware, they had re - VEM 9-14 and the old 6 VEM and associates of the Channel ports, are orphans.
By example, if we look at the port-channel 2 more in detail, we see orphans 3 VEM-related sound and it has no ports associated with it:
Sho vsm21a(config-port-Prof) # run int port-channel 2

Lighthouse is off
Input stream control is turned off, output flow control is disabled
Switchport monitor is off
Members in this channel: Eth3/4, Eth3/6
Final cleaning of "show interface" counters never
102 interface resets
We can probably remove the port-channel 2, but assumed that the error message on the port-profile in use is cascading on the other channel ports. We can delete the other port-channel 4,6,8,10 orphans and 12 as they are associated with the orphan VEM, but we expect wil then also get errors on the channels of port 13,15,17,19,21 and 23 who are associated with the MEC assets.
We are looking to see if there is an easy way to fix this on the MSM, or if we need to break one of the rising physical on each server, connect to a vSS or vDS and migrate all off us so the Nexus 1000V vmkernel ports can clean number VLAN.
You will not be able to remove the VLAN from the system until nothing by using this port-profile. We are very protective of any vlan that is designated on the system command line vlan.
You must clean the canals of old port and the old MEC. You can safely do 'no port-channel int' and "no vem" on devices which are no longer used.
What you can do is to create a new port to link rising profile with the settings you want. Then invert the interfaces in the new port-profile. It is generally easier to create a new one then to attempt to clean and the old port-profile with control panel vlan.
I would like to make the following steps.
Create a new port-profile with the settings you want to
Put the host in if possible maintenance mode
Pick a network of former N1Kv eth port-profile card
Add the network adapter in the new N1Kv eth port-profile
Pull on the second NIC on the old port-profile of eth
Add the second network card in the new port-profile
You will get some duplicated packages, error messages, but it should work.
The other option is to remove the N1Kv host and add it by using the new profile port eth.
Another option is to leave it. Unless it's really bother you no VMs will be able to use these ports-profile unless you create a port veth profile on this VLAN.

1000V - Importance of the ' system vlan "in port-profile
Hi all
Can someone help me understand the importance of the command "system vlan" in a profile of port?
As I understand it, it was used to mark the criticisms of the system VLAN (package, data, etc.) to their config was pushed to vCenter so that they would continue to work the MSM should be down. Is this fair?
All of the examples I have watch seems to just mark every VLAN (data VM even VLAN) as "system vlan" in their profiles of prot ethernet uplink. Now that is best practice?
In addition, there is a reason to mark vEthernet with control panel ports vlan?
See you soon,.
P
As you already wear that system vlan is to ensure access to the vlan vsm to go down and then the esxi host is reset. If the system vlan was not enabled host esxi would not be able to talk to the vsm, but this is only the case if the management port using the Cisco VDS and not a VSS or VDS.
as I mainly use servers with only 2 ports 10 GB I use system VLAN for ESXi management / storage and vMotion and if the vCenter is a virtual machine, then also the vlan that uses. all other VLANS I don't not in the category system VLAN.
I use also a VSM Layer 3 so no need to worry the VLAN the packet and data. But I use that I have several farms esxi in a different subnets from the management and the 1000v in a subnet for network management.
I hope this helps.

How to remove the system idle from dashboard?
Hi all!
Anyone know how to remove the system idle from dashboard?
It is possible at all?
Thaks.
No, you can't "remove them from the dashboard.
You would turn them off (aka set them as inactive), and this would remove them from all reports.

There is Nothing to "remove, disable or close. "System Idle.
Process' is not at all no problem. 'Rest' means not "in use." It's
just the name for the system when it does not
whatever it is. It is there just to make the total adding up to 100%.If you see reading of 70 to 99%, so that means you actually use
only 1% to 30%. This is quite normal. Nothing to worry about.Ken Blake

Win XP: Remove the 'System' of the 'My Documents' folder attribute
Win XP: The 'My Documents' folder contains an attribute of the system. Now, I can't save file there. How can I remove the attribute "system"?
If you look at the security for 'My Documents' tab, you will see that the system has access to the file, but it should not have attribute on the file system.
Access special permissions and see who is the owner of the folder. It should be yourself. If this isn't the case, you may need to take ownership of the folder to get access.
I hope this helps.

Windows 7 - How to remove the 'system reserved' after installation
I do not have a separate HDD called system reserved in my computer. It takes approximately 100 MB of space, but I never agreed to be installed separately.
Can I format to get rid of him, or even delete or move somewhere? I do not have to reinstall Windows 7 to do this, because it takes time for all the programs to be reinstalled...
Any suggestions of what could be done without having to reinstall Windows 7 new would be greatly appreciated. I would like to know if it's possible. Thank you.
I would say that that keep the system reserved. It is a very convenient tool created by MS in case of emergency
The following link will give you a better idea: http://social.technet.microsoft.com/Forums/en-US/w7itproinstall/thread/29fa0858-8971-413b-ba8a-d033aa6dae55
You can delete system reserved partition, but if you happen to remove it, then you will not be able to use the bitlocker feature

Remove the system image?
I want to delete an image of my hard drive system. I found the following tips:
Click on start-> Search: backup-> open "Backup and Restore"-> click on 'Manage space'-> Delete
Unfortunately when I do that, there is no option 'manage space '. I use Windows 7...
Any advice?
You get this screen under one of the following conditions:
- No replacement was ever conducted on this machine.
- The backup of the image that you want to remove was created on another computer.
- Someone has been removed and catalogs backup in the C:\System Volume Information folder.
Now, you must manually remove the files from the image.

How can I get rid of these files? What do I do? seems to be a waste of space if I don't empty them.
Hi russellinspain,
Run the disk cleanup utility should delete these files. You can remove the files if you want to save space on the hard disk.
Try to delete the files as an administrator. To do this, try the following steps.
a. Click Start, type disk cleanup, click with the right button on disk cleanup and click Run as administrator.
b. place a checkmark on "System error memory dump files"
c. click ok and check if the files are deleted successfully.See Delete files using disk cleanup

How to remove the system reserve of my computer?
I installed Windows 7 Pro in Windows 7. I used a program of virtual drive to mount the iso of Windows 7. I then install Windows 7 pro. I started out in the 'new' Win 7 and let Windows do its thing updated and which do not. I have a Windows.old so I know that the operation went well. However, when I open the computer, he showed my C drive and an extra drive that I have 'E', but he also showed the system reserve partition drive. I know that this is part of the startup procedure so I know not, I can't delete it, but how do I remove it from my computer, where it shows all the readers of mjy? It wasn't until I reinstalled Windows (by that I mean the partition was there but does not in the window of the computer).
To my knowledge, the partition of the reserve of should not be assigned a drive letter so do not appear in the window of the computer. My score is assigned to the letter GHello
Usually system reserved partition will not be assigned a drive letter. However, as you can see the score with a drive letter, I suggest you to refer to the article and remove the assigned drive letter:
Change, add, or remove a drive letter
http://Windows.Microsoft.com/en-in/Windows7/change-add-or-remove-a-drive-letter
Once you remove the drive letter, it will not in the computer.
It will be useful.

Removed the system restore points
I tried to install Samsung Kies and Samsung mobile driver, once I did and had problems, then I tried to uninstall, I went to the restoration of the system and realized that all the points that have been created have been deleted. I have a lot of space on my computer and the system restore is enabled. Is there anyway that I can get back them? I ran a virus scan and all is well, but I'm just worried for where my points went.
Thank you
They are automatically deleted after they are no longer relevant, or if the space that you book for them runs. You can drag the slider in your settings to reserve more space for their own good:

Hi all
I understand that this vlan system allows the traffic flow for the vlan was VSM is not accessible, and vlan system should NOT be normal machine virtual traffic vlan. In my deployment of a normal vSphere environment with N1kv, I'll put these VLANS as system vlan: ESXi Mgmt N1kv mgmt, control & package, VMotion, storage over IP.
I put the VLANs as system vlan on the uplink port profiles and indivdual port profiles for each VIRTUAL local area network. Correct me if that's wrong.
What should be system vlan, or what those who shouldn't be system vlan? VMotion vlan? What are the disadvantages to specify all the VLANS as system vlan? Is it not better because even if VSM fell for a reason, MEC will still send traffic for all virtual machines?
Thank you
Ming
Ming,
Your understanding of the system VLAN is not totally accurate. All them VLAN will be forwarding the case where your VSM is not accessible. Each MEC module will continue to pass system and non-vlan traffic if the VSM is offline. EACH MEC will keep its current programming, but will not accept any changes until the VSM is back online. System VLAN behaves differently that they will always be in a State of transfer. VLAN systems will transmit the traffic even before that a MEC is programmed by VSM. That is why some system profiles demand them - IE. Control/package etc. These VLANs must be transferred in ORDER for the MEC to talk to the VSM.
As for your list of "what should be system VLAN"-remove VMotion. There is no reason that your VMotion network should be defined as a system of VIRTUAL LAN. All the others are correct.
Also remember that you can ONLY define a VLAN on the port profile an uplink. So if you use an uplink for 'system' type traffic and the other for traffic of type "Data VM", you would have just any single VLAN 'authorized' on an uplink - not both. Allowing them the time will cause problems. The only case, you have to keep in mind is that for a "system vlan" to apply, it must be defined on the Port of vEthernet profile and a profile of Uplink Port.
E.g.
Let's say my Service Console uses VLAN 10 and my VMs also use the VLAN 10 for their data traffic. (Bad design, but just to illustrate a point).
VLAN in "two places" seen set the system would you allow to treat ONLY the traffic of your "Service Console" as a traffic system and always apply security programming for your traffic "VLAN Data. After a reboot, you Console of Service traffic would be routed immediately, but your VM data would not be until the MEC had pulled the programming of the VSM.
