etherchannel and spanning-tree

EtherChannel considerations
info http://packetlife.net/blog/2010/jan/18/etherchannel-considerations/

Hi

I was doing a bit of searching on PAgP & LACP and found this, thought it might come in handy for some. I never realised the commands did what is stated below, must have missed this in the book or had one too many wines at that point 

http://www.edgenetworks.nl/etherchannel.html

channel-group [#] mode on (disables PAgP en LACP)

channel-group [#] mode off (disables PAgP en LACP and prevent the ports to form a port-channel)

channel-group [#] mode auto (use PAgP in a passive mode, it will wait until a PAgP packet will be send)

channel-group [#] mode passive (use LACP in a passive mode, it will wait until a PAgP packet will be send)

channel-group [#] mode desirable (use PAgP in an active mode, it will start to send  PAgP packets)

channel-group [#] mode active (use LACP in an active mode, it will start to send  LACP packets)

假設現時有 16 個 Port 在同一個 EtherChannel，由於所有 Port Priority 預設都是 32768，因此系統選擇 Port ID 最小的 8 個 Port 成為 Active Port，其他則成為 Hot Standby。

2. Spanning-tree

vSphere doesn't show health status for the server / pwhicu / vmware VIM_VCDB clean up as Vmware support team do

problem : health status monitoring alert , not show , keeping show blank and 

vCenter Service Status show blank

Health status alarms can also be associated with vCenter services.

In your vSphere client go to the home page with the tiered icons, in Administration, go to "vCenter Service Status" and you'll probably find something in there that is causing the alarm to be triggered.

 No Service "vCenter Single Sign-on " running or installed . ( due to vmware auto update uninstalled) ?

I'm not sure if this is too late (or now irrelevant), but just in case a quicker way is wanted, you can restart the necessary service through vSphere Client:

Click the affected Host(s) in vCenter

Click Configuration

Click Security Profile

Click Firewall Properties

Highlight CIM-Server

Click Options

Click Restart

result : not work . 

then , manual , stop and then start . 

status : show running afterward 

follow up : REMEMBER to click update (if present , not blank) . then wait in "Hardware Status" tab for 5 mins . (this confirm not work)

VMWARE VCENTER DATABASE OVER 10 GIGA

Database Size: How to Increase Sql Database Size

$query = ("SELECT * FROM $db WHERE conditions AND LEN(col_name) = 3");

[SOLVED] Large disk space consumption in C:\ProgramData\Acronis\BackupAndRecovery\MMS\Catalog\

https://forum.acronis.com/forum/acronis-backup-recovery-10-11-forum/solved-large-disk-space-consumption

Hello,
I got a instance of ABR 11 for Windows Deployed on a Windows 2008 R2 x64, ABR11 is the result of an upgrade ABR 10.

ABR 10 was installed on disk C (40Gb for OS only)

Since ABR 11 is deployed, we experiences lack of disk space on system disk C.
After investigations, we found that Acronis took between 6 and 11Gb in the Acronis directory :
C:\ProgramData\Acronis\BackupAndRecovery\MMS\Catalog\A1B35874-6F6B-8536-1104-C552CE5851A5\002F28D8-719B-4FF5-BE8C-79951BCAF8AF\Index\ with larges files (2/3Gb) called like 7F51FF1D-99D9-4DF1-A12B-688E12097320 ...

Is there a way to stop this behavior ? No more big 3GB files in this système directory? Create this file on the backup volume next to the .tib files (There is a Catalog directory with similar files in int (naming + size)

Thanks for your support.
Best regards,

Julien Duvault

Hello Julien,
the files in the system directory are just the cache of the files residing next to the .tib files. You can delete them, but they will be recreated as soon as you address to the vault where the tibs are. For now, the only way to stop this behavior is:
1) to switch off cataloging (Edit backup plan > Plan parameters > Backup options > Backup cataloging)
2) to delete the files manually from both the system directory and the vault you are backing up to.
A kind of cataloging still will be performed, but the files will not be so huge.
