Some of these customer’s run their VMFS datastores hot >80% and these alerts/alarms were triggering. Monitors whether the thin provisioning threshold on the storage array exceeds for volumes backing the datastore. As a VMware admin, you may be familiar with “ Datastore usage on disk ” and “ Thin-provisioned volume capacity threshold exceeded ” alerts Thin-provisioned volume capacity threshold exceeded Interestingly, this first issue was blocking their efforts to actually test VMware vSphere vVols on Hitachi VSP Storage. So first to the alarms/alerts on VMFS datastore usage. I'll also share some insights on how customers are dynamically reclaiming storage as they expand their vVols footprint in a part 4. They were evaluating/engineering an architecture around VMware vSphere vVols but wanted to get their existing VMFS datastores spring-cleaned. In this part 1, I’ll address vCenter datastore alarms/alerts they were dealing with and in part 2, I’ll address the steps required if you want to verify automatic unmap for VMFS6 datastores down to unmap I/Os and in part 3, what we provided to enable them with some UNMAP powercli automation for their existing VMFS 5 datastores. movescount.I recently encountered a cluster of customers who were dealing with datastore space management issues. Latest #Move, Trail running 32min, hard, 3.18 mile. Latest #Move, Trail running 2h, hard, 12.09 mile. Latest #Move, Trail running 1h 31min, moderate, 8.52 mile. Now you should have a lot fewer datastore warning alarms.īlackberry CCIE Celerra cisco Citrix DCNM EMC Exchange FCoE gmail MDS Microsoft Nexus NX-OS pvs SRM UCS UCS-D UCS Director uda vmware vsphere windows2008 xenapp xendesktop xenserver Manage Configure the “Datastore usage on SAN Disks” trigger to alarm a warning at 70% and alert at 85%.Create a new alarm at the SAN-DATASTORES level named “Datastore usage on SAN Disks”.Configure the “Datastore usage on LOCAL Disks” trigger to alarm a warning at 90% and alert at 95%.Create a new alarm at the LOCAL-COS-DATASTORES level named “Datastore usage on LOCAL Disks”.Go to the alarm definition for “Datastore usage on disk” and disable it by clearing the Enable this alarm box.Drag and drop the local VMFS datastores into the LOCAL-COS-DATASTORES folder and the SAN datastores into the SAN-DATASTORES folder.Right-click on your datacenter and create two new folders, one named LOCAL-COS-DATASTORES and one named SAN-DATASTORES.Go to the Home –>Inventory->Datastores view in the vSphere Client.I have found that the following procedure is the best way to prevent this alarm on the local VMFS datastores. If anyone knows why this is beneficial I would love to here from you.Īnyway, back to the “Datastore usage on disk” alarm issue. I still have yet to understand why VMware decided to put the COS in a VMDK. 95% of the time this alarm is in a warning state because of the local VMFS data store that is required in ESX 4 for the Service Console OS to live in. One of the pre-configured alarms that seems to always be in a warnings state is the “Datastore usage on disk” alarm. There are several alarms that are configured out of box and defined at the topmost vCenter server level. With vCenter 4.x VMware addressed this by giving admins the ability to create alarms for just about any event on any object. One of the complaints of vCenter 2.x was the limited number of alarms that could be configured.
