Vmfs Datastore Inaccessible Updated - Vmware
| Area | Best Practice | |-------|----------------| | | Use active-active arrays or properly configured ALUA. Avoid active-passive without failback automation. | | Multipathing | Set Round Robin (VMW_PSP_RR) for FC/iSCSI. Adjust IOPS limit (default 1000). | | Monitoring | Configure SNMP traps for APD/PDL events. Monitor esxcli storage core path stats . | | Backup | Regular VM-level backups (Veeam, Commvault). File-level backup of critical VMX/VMDK. | | Capacity | Enable Storage DRS to prevent 100% full datastores. Set alerts at 85% usage. | | Patch management | Keep ESXi updated; VMware has fixed numerous VMFS3/VMFS5 heartbeat bugs (e.g., KB 2149275). | | Change control | Coordinate any LUN masking, zoning, or controller firmware upgrades with vSphere administrator. |
