Problem Description

aSEC has security protection enabled, and VM has security components installed. The following scenarios may cause Take Snapshot

  1. When a ransomware incident occurs or a malicious damage incident is reported, the background response logic will be triggered. The background will automatically create a suspected ransomware snapshot or malicious damage snapshot for the VM/Virtual Machine Take Snapshot fails.

  2. VM/Virtual Machine performs emergency recovery for ransomware, and the user fails to proactively create a snapshot to retain the ransomware scene

  3. VM/Virtual Machine handles a security incident or fixes a vulnerability, the snapshot created proactively fails to handle or fix the vulnerability

Warning Information

none

Effective troubleshooting steps

  1. Check the prerequisites

– VM HCI cluster where the virtual machine/Virtual Machine Cluster >= 3 node

– Whether the HCI Cluster has created VS storage

– VM the storage location of the virtual machine/Virtual Machine

  1. Check the HCI Cluster and VS storage status

– Check whether the HCI Cluster status is normal

– Check the VS storage Cluster the HCI cluster to see if it is normal

  1. Troubleshooting vs. storage capacity
  • Check the VS storage capacity on the HCI Cluster to see if it is within the normal snapshot threshold range.

Root Cause

  1. aSEC snapshots only support Storage Based Snapshot, not disk based snapshot

  2. The HCI Cluster status or VS storage status is abnormal

  3. VS storage capacity is insufficient to take snapshots

Solution

  1. aSEC snapshots only support Storage Based Snapshot, not disk based snapshot. The following prerequisites must be met

– HCI Cluster>=3 node

– Create VS storage

– The storage location of the VM/Virtual Machine is on the VS storage (change the storage location to the VS storage)

  1. The HCI Cluster status or VS storage status is abnormal

– HCI Cluster status is normal (aSec fails to call the HCI interface due to abnormal status. Try to restore it to normal status or contact HCI technical support for processing)

– The VS storage status is normal (the snapshot fails due to abnormal storage status, please contact VS technical support for processing)

  1. VS storage capacity is insufficient to take snapshots

– The VS storage capacity is within the threshold range for snapshots (snapshots fail due to insufficient storage capacity, clear and release storage space)
