Summary
- Slow performance
- Unpredictable failures
- Disk corruption, or virtual machine corruption
- Alerts or alarms being received
- Need to know best practices on how to properly setup and maintain an environment
Best practices and Informational:
- vSphere Storage Appliance (VSA) networking best practices (2007363)
- VMware vSphere Storage Appliance FAQ (2001389)
- Minimum required permissions for Storage VMotion (1011345)
- Tuning ESXi/ESX for better storage performance by modifying the maximum I/O block size (1003469)
- Microsoft Clustering on VMware vSphere: Guidelines for Supported Configurations (1037959)
- Testing virtual machine storage I/O performance (1006821)
- Understanding virtual machine snapshots in VMware ESX (1015180)
How to:
- Removing a LUN containing a datastore from VMware ESXi/ESX 4.x (1029786)
- Increasing the block size of local VMFS storage in ESX 4.x during installation (1012683)
- Getting started with the VMware vSphere Storage Appliance (2009895)
- Changing a LUN to use a different Path Selection Policy (PSP) (1036189)
Storage vMotion issues:
- Storage vMotion fails with a generic DMotion error (1009113)
- Using Storage vMotion to migrate a virtual machine with many disks timeout (1010045)
- Storage vMotion fails with the error: virtual machine has virtual disk in link-clone mode (1014249)
- Storage vMotion fails at 18% with the vmware.log error: Cannot allocate memory (1020695)
- Storage VMotion operation fails with the error: Insufficient disk space on datastore (1008171)
- Moving a single virtual disk using Storage vMotion via the command line (1004040)
Snapshot issues:
- Consolidating snapshots (1007849)
- Consolidating snapshots in vSphere 5.x (2003638)
- Taking a snapshot with virtual machine memory stuns the virtual machine while the memory is written to disk (1013163)
- Unable to use Snapshots or perform a backup on virtual machines configured with bus-sharing (1006392)
- Delete All snapshot operation results in a Consolidate Helper snapshot when a datastore has insufficient disk space (1003302)
Local storage issues:
- Unable to install ESXi/ESX on local storage as the disk is grayed out (1011695)
- Troubleshooting poor local storage controller performance (1007688)
- Adding an extent to a VMFS volume fails after increasing local storage space (1002821)
- System does not clear RAID controller cache during shutdown (1012794)
Microsoft Clustering issues:
- ESX machines hosting passive MSCS nodes report reservation conflicts during storage operations (1009287)
- Microsoft Cluster Service (MSCS) support on ESXi/ESX (1004617)
- ESXi/ESX hosts hosting passive MSCS nodes with RDM LUNs may take a long time to boot (1016106)
- ESX Server Support for Microsoft Clustering Service with Windows 2003 SP1, R2, and SP2 (2021)
- Operating system drives of a MSCS cluster must be configured on local storage (1002875)
Storage arrays:
- Physical drive failure on a storage array (1003499)
