When the Stargate service becomes unavailable on a single CVM on an AHV node, the iSCSI redirector is used to maintain I/O operations in the cluster. The iSCSI redirector ensures that vDisk I/O is redirected to other accessible CVMs, maintaining the availability and functionality of the storage operations within the Nutanix cluster.
Option B. iSCSI redirector is what AHV uses to redirect vdisks to be hosted by other CVMs when the local CVM is inaccessible via iSCSI (e.g. CVM is down or Stargate is having issues). https://portal.nutanix.com/page/documents/kbs/details?targetId=kA00e000000CuaDCAS
Agree with B
Answer is B https://www.nutanixbible.com/5b-book-of-ahv-how-it-works.html
B would be correct: CVM Autopathing (ha.py) - for ESXi and Hyper-V; iSCSI multi-pathing - for AHV.
