iSCSI datastore reconnects read only after outage

Scenario

A storage outage clears, but the reconnected volume or datastore returns in read-only or degraded mode.

Recommended Resolution Path

1. Check storage controller logs and host multipath status before writing anything new.
2. Confirm whether the file system or datastore requires a consistency check.
3. Review whether one path or controller is still unhealthy after the outage.
4. Do not force write operations until you are confident the storage state is stable.

Technician Notes

Document what changed, what confirmed the fix, and whether the issue points to a broader standards gap worth addressing for the client.
