![]() ![]() ![]() Ĭheck that a rescan does not restore visibility to the targets. Identify the available storage paths to the reported storage device by running esxcfg-mpath - l. Use the following guidance to determine the cause of the failure or to eliminate possible problems. Path Element | Failure Point - vmhba35 | HBA (Host Bus Adapter) C1 | Channel T0 | Target (storage processor port) L7 | LUN (Logical Unit Number or Disk Unit). The storage device path, for example, vmhba35:C1:T0:L7, contains several potential failure points: Host(s) lost redundancy to storage device(s) (fault symptom). The alert will then be canceled automatically.ĭatastore has one or more hosts that have lost redundant paths to a storage device. If storage connectivity for the devices indicated is caused by a permanent loss or change, you must cancel the fault alert as a workaround. If storage connectivity is restored for all of the affected host and storage device combinations, the fault is cleared and the alert canceled. You must rescan after making changes to make sure that the targets are detected. ![]() For more information about configuring the fiber switch, seeįinally, check the following physical hardware: the storage processors on the array, the fiber switch and the Gigabit Interface Converter (GBIC) units in the switch, the fiber cables between the fiber switch and the array, and the array itself. The fiber switch propagates RSCN messages to the ESX hosts. If you require assistance, contact your switch vendor. The fiber switch zoning configuration permits the ESX host to see the storage array. To troubleshoot the connectivity to the fiber-attached storage, check the fiber switch. Check that the following physical hardware is functioning correctly: Ethernet switch, Ethernet cables between the switch and the ESX host, and Ethernet cables between the switch and the storage array.For more information, contact your storage vendor. Check that the initiator is registered on the array.Check whether a vmkping to each network portal of the storage array fails.Check whether a ping to the storage array fails from ESX.Troubleshoot the connectivity to the iSCSI storage by using the software initiator: Determine whether the connectivity issue is with the iSCSI storage or the fiber storage. For information on rescanning the storage device by using the command-line interface and the vSphere Client, see. Check that a rescan does not restore visibility to the targets. To determine the cause of the failure or to eliminate possible problems: Identify the available storage paths to the reported storage device by running esxcfg-mpath - l. The storage device path, for example, vmhba35:C1:T0:L7, contains several potential failure points: Path Element | Failure Point - vmhba35 | HBA (Host Bus Adapter) C1 | Channel T0 | Target (storage processor port) L7 | LUN (Logical Unit Number or Disk Unit). Host(s) lost connectivity to storage device(s) (fault symptom). If SCSI devices are detached or permanently removed, you must manually cancel the alert.ĭatastore has lost connectivity to a storage device. The fault will be resolved and the alert canceled if the device is turned on. Storage device has been turned off administratively (fault symptom).Īsk the administrator about the device state. ImpactĪ storage device for a datastore has been detected to be off. These alert definitions have the following impact and criticality information. The vCenter adapter provides alert definitions that generate alerts on the datastore objects in your environment. ![]()
