*Tested works for vSphere 4 & 5

http://IPADDRESSorDNSNAMEofVCENTERorHOST/mob

20111209: How to Reboot or Reset a HA Protected VM (HVM) on a Citrix XenServer Host

1 - "xe vm-list" to get the uuid of the VM that is hung

2 - "list_domains" to list the domain uuid's so you can determine the domain # of the VM above by matching the uuids from this output with the uuid for your VM from the previous command.

3 - "/opt/xensource/debug/destroy_domain -domid XX" where XX is the domain number from the previous command

(note: if you don’t run 2 and 3 in a HA environment, you get the error "The operation could not be performed because a domain still exists for the specified VM")

4 - "xe vm-reboot uuid=XXXX --force" where XXXX is the uuid from the first vm-list command for your VM (or “xe vm-reset-powerstate=XXXX --force")

Historical Notes: Exchange 2007

Setting Identities for use with Outlook Anywhere (on CAS server):

Get-ClientAccesServer | FL

Set-ClientAccessServer -Identity "mbx1" –AutodiscoverServiceInternalURI https://nlb.nwtraders.msft/autodiscover/autodiscover.xml

Get-WebServicesVirtualDirectory | FL

Set-WebServicesVirtualDirectory -Identity "mbx1\EWS (Default Web Site)" –InternalUrl https://nlb.nwtraders.msft/EWS/Exchange.asmx

Get-OABVirtualDirectory | FL

Set-OABVirtualDirectory -Identity “mbx1\OAB (Default Web Site)” -InternalURL https://nlb.nwtraders.msft/OAB

Enable-OutlookAnywhere -Server mbx1 -ExternalHostname “nlb.nwtraders.msft” -ClientAuthenticationMethod “NTLM”

Get-ActiveSyncVirtualDirectory | FL

Set-ActiveSyncVirtualDirectory -Identity “mbx1\Microsoft-Server-ActiveSync (Default Web Site)” -InternalURL https://nlb.nwtraders.msft/Microsoft-Server-Activesync

*Can substitute ExternalURL for InternalURL in the above

Historical Notes: ESX 3.5

Enable root SSH login on an ESX host:

Either create a user and 'Grant shell access' to the user via the VI Client, login to SSH using that account, and “su –” to switch to root user.

or access CLI via console connection using iLO/ DRAC/ KVM/ ….

nano /etc/ssh/shhd_config

Edit the line that starts with PermitRootLogin and change the no to yes.

Press Ctrl-O and then Enter to save the file. Exit with Ctrl-X.

service sshd restart

Restart Management Agents on ESX host:

service mgmt-vmware restart

Some Deletables:

vmware-XX.log (vmware.log is the active log)

.vmss (these files are generated when the VM is suspended, so if the VM is not currently in a suspended state then safe to delete)

...-zdump.XXX (dump files generated when a guest hangs)

vmware-XX.log.vzsnp (vRanger copies of all files under 1MB that get left behind if a backup job does not complete.)
