VMware: VMware Data Recovery: The Unmount operation failed because the Destination may be in use

May 24th, 2011 1 comment

After some failed backups and warnings in the even log I decided to troubleshoot the backup job. I tried to remount my “storage destination” but received this warning:

The Unmount operation failed because the Destination may be in use. Please try again later

Solution:

After reading KB1018060 and removing the store.lck file I was able to re-open/dismount/mount the storage destination again

image

Browse to the BackupStore folder:

cd /SCSI-0\:1/VMwareDataRecovery/BackupStore/

Remove the lock file:

rm -rf store.lck

VMware: SCSI reservation conflicts

December 23rd, 2010 5 comments

Last week I had some trouble by a customer, 4 of my 8 datastores aren’t visible/accessible on the 6 ESX 3.5u2 hosts connected to a (FC) HP MSA1500.  Some datastores become unavailable and some were not affected. Numerous VMs were down, some of those with warning messages like Orphaned and Inaccessible.

Oke.. let’s troubleshoot:

 

Checking for active paths: esxcfg-mpath -l | grep -i active

FC 6:2.1 210100e08bb27a58<->500508b30091aac9 vmhba1:0:2 On active preferred
FC 6:2.1 210100e08bb27a58<->500508b30091aac9 vmhba1:0:6 On active preferred

FC 6:2.1 210100e08bb27a58<->500508b30091aac9 vmhba1:0:4 On active preferred

All online!

Checking for death paths: esxcfg-mpath -l | grep -i death

[root@esxmeri01 /]#

None death paths!

 

Checking my HBA’s connected to the SAN: cd /vmfs/devices/disks and listls vmh*

vmhba1:0:1:0  vmhba1:0:2:1  vmhba1:0:4:0  vmhba1:0:5:1  vmhba1:0:7:0  vmhba2:0:0:1   vmhba2:0:0:3  vmhba2:0:0:6  vmhba2:0:0:9

VMware: HP Management Agent “An active Virtual Machine [ IP] has been detected on host”

October 4th, 2010 3 comments

Today I was busy to to install some HP Managent Agents 8.60 on a DL380 G6, after entering the host in maintenance mode, extracting the HP software in the /tmp/ folder I was ready to install the agent. By running the command “./install860.sh –install” I received the warning that some VM’s still running and must be powered down before you install the agent, warning:

An active Virtual Machine [ ***.***.***.*** ] has been detected on host [*****.*****.local]

And:

Please modify the state of the VMs to be Suspended or powered off and then retry Agents Installation.

See full message log:

 

[root@********* 860]# ./install860vibs.sh –install

HP Insight Manager Agent 8.6.0-11 Installer for VMware ESX
Target System is VMware ESX 4.0.0 build-208167
Server:  ProLiant DL380 G6

This script will now attempt to set ESX Host in Maintenance Mode
for IM agents install.
Do you wish to continue? (y/n) y

(vim.fault.NotFound) {
   dynamicType = <unset>,
   faultCause = (vmodl.MethodFault) null,
   msg = "Unable to find a VM corresponding to "***.***.***.***"",
}
(vim.fault.NotFound) {
   dynamicType = <unset>,
   faultCause = (vmodl.MethodFault) null,
   msg = "Unable to find a VM corresponding to "***.***.***.***"",
}
An active Virtual Machine [ ***.***.***.*** ] has been detected on host [*****.*****.local]

The ESX host will be put into maintenance mode
   to be able to install/uninstall the agents.
The Virtual Machines must be either Powered off or Suspended
   by the operator to allow the transition
   of the ESX host into maintenance mode.
Please modify the state of the VMs to be Suspended or powered off
   and then retry Agents Installation.

VMware vSphere 4.1 released today!

July 13th, 2010 1 comment

Today VMware released the newest version of vSphere, version 4.1 🙂

 

Whats new:

Scripted Install for ESXi. Scripted installation of ESXi to local and remote disks allows rapid deployment of ESXi to many machines. You can start the scripted installation with a CD-ROM drive or over the network by using PXE booting.

vSphere Client Removal from ESX/ESXi Builds. For ESX and ESXi, the vSphere Client is available for download from the VMware Web site. It is no longer packaged with builds of ESX and ESXi.

Boot from SAN. vSphere 4.1 enables ESXi boot from SAN (BFN). iSCSI, FCoE, and Fibre Channel boot are supported.

Hardware Acceleration with vStorage APIs for Array Integration (VAAI). ESX can offload specific storage operations to compliant storage hardware. With storage hardware assistance, ESX performs these operations faster and consumes less CPU, memory, and storage fabric bandwidth.

Storage Performance Statistics. vSphere 4.1 offers enhanced visibility into storage throughput and latency of hosts and virtual machines, and aids in troubleshooting storage performance issues. NFS statistics are now available in vCenter Server performance charts, as well as esxtop. New VMDK and datastore statistics are included. All statistics are available through the vSphere SDK.

Storage I/O Control. This feature provides quality-of-service capabilities for storage I/O in the form of I/O shares and limits that are enforced across all virtual machines accessing a datastore, regardless of which host they are running on. Using Storage I/O Control, vSphere administrators can ensure that the most important virtual machines get adequate I/O resources even in times of congestion.

VMware: Snapshot operation exceeded the time limit for holding off I/O in the frozen virtual machine

June 1st, 2010 14 comments

After installing VMware Data Recovery I scheduled a fresh job to make a backup of my VM’s in the datacenter. The first 8 VM’s backuped successful, but the VM’s with a iSCSI target (Exchange, SQL) crashing after creating virtual machine snapshot. I received this error:

Creating a quiesced snapshot failed because the created snapshot operation exceeded the time limit for holding off I/O in the frozen virtual machine.

VMware: Configure OpenFiler iSCSI targets for VMware ESX

May 25th, 2010 1 comment

Last weekend I downloaded the OpenFiler v.2.3 iso to configure the Central Storage solution in my homelab. After installing the software in a new VM I figured out how to configure iSCSI targets and present them to my ESX servers…

I’m running both VMware ESX 4.0 and ESXi 4.0 in my lab and both provide iSCSI functionality by default to connect through to an iSCSI target.

After I installed OpenFiler in a VM I connected to https://ip:446, you can manage your service account with the created root account and you can manage the OpenFiler with the following credentials Username: Openfiler Password: password

My configuration staps…

.

Configure OpenFiler:

Create a new volume group:

 

1. Physical Volume – Assigning space on a physical disk for use in a Volume Group.

2. Volume Group – Contains Physical Volumes from which a Logical Volume will be created.

3. Logical Volume (LUN) – This is what is presented through to a server

image

– Select volume and give a volume group name (in my case VMpros)
