Troubleshooting Ultra High Performance Volume Attachments

This topic covers troubleshooting steps you can take as well as prerequisites to verify for volumes configured for the Ultra High Performance level where either the volume fails to attach or the volume attachment is not multipath-enabled.

Troubleshooting Volume Attachment Failures

The Block Volume Management plugin is required for volumes configured for Ultra High Performance , attached using the iSCSI attachment type. If the volume fails to attach to the instance, the issue is likely caused by incorrect configuration for the Block Volume Management plugin. See the troubleshooting suggestions in this section for these issues.

Volume Attachment is not Multipath-Enabled

When you attach a volume configured for the Ultra High Performance level, to achieve the optimal performance, the volume attachment must be multipath-enabled. The Block Volume service attempts to enable the attachment for multipath when the volume is being attached. If not all of the prerequisites have been addressed, the volume attachment will not be multipath-enabled.

If your volume is not configured for multipath, to troubleshoot the issue, review the information covered in this section and address any issues raised.
