Hi,
I am not sure if this is the right place to post workarounds/fixes, if not
please advise. Fix only tested in CCP 4.3.0.2
Cause:
1. Migrating a VM outside of CloudPlatform/ACS using VMware Storage Live
Migration (VMs are online when performing this move)
2. VM Agent does not register Storage Path Change
Effect:
1. VMs might randomly shutdown (Protection mechanism)
2. Starting VMs from UI will fail
3. Any storage changes will not work
a. Modifying Volume size
b. Deleting Volumes
c. Snapshots (Disk & VM)
4. Many Errors/Warnings in MS Log Files
Workaround/Fix
1. In CloudPlatform/ACS Locate the ID of the store where you Storage
vMotioned the VM to:
a. i.e. Storage Pool Name = <Storage Pool ID>
2. In CloudMonkey, locate the VM where the changed Volumes are and note
the ID of the VM:
a. list virtualmachines instancename=<The VMs Instance Name> listall=true
filter=name,id
3. In CloudMonkey, list all the Volumes of the above VM:
a. list volumes virtualmachineid=<Virtual Machine ID> listall=true
filter=name,storage,storageid,id,path
4. Take note of the following:
a. Name – It will reference to the Volume which needs to be migrated
b. Storage – Where the Volume resides in the CloudPlatform/ACS DB
c. Storageid – The Storage ID of the OLD Datastore (This ID needs to be
changed in the command below)
d. Path – The Physical .VMDK filename in the NEW datastore
5. In CloudMonkey, update the VM’s “Storageid” and “Path”
a. update volume id=<Volume ID> storageid=<Storage ID> path=<.VMDK
Filename – without the .VMDK extension>
6. In CloudMonkey, run the following command to ensure that the storage
location has been changed:
a. list volumes virtualmachineid=<Virtual Machine ID> listall=true
filter=name,storage,storageid,id,path
i. Confirm
STORAGE change
ii. Confirm
STORAGEID change
iii. Confirm
PATH change

Subject: VMware Storage vMotion
Hi,
Is it possible to migrate VM Instance storage outside of ACS? Specically, can
you use VMware’s Storage vMotion instead of powering down the VM first?
I have tested this and it seems that the VM is fine, but the DB has not updated
the new location
Running CCP 4.3.0.2
