Session Summary

Responded to a VWP G: drive outage. The Dell R740 Hyper-V host (VWP-HYPERV1, 172.16.9.184) crashed overnight at 04:31 UTC with CRITICAL_PROCESS_DIED, taking down the VWP-FILES VM and making the entire G: drive inaccessible to staff. Staff could not access the Orders application or any G: drive data.

Investigation revealed VWP-HYPERV1 was offline (not responding to ping, GuruRMM agent last seen 04:31 UTC). Located the iDRAC at 172.16.9.151 using the same credentials as VWP-QBS iDRAC from the vault. Confirmed the server hardware was powered on but the OS was not booting. Sent a ForceRestart command via the iDRAC Redfish API.

During POST, user reported the RAID controller detected a "foreign configuration" that required importing. This is identical to the pattern seen during the 2026-04-22 HP ProLiant NVRAM corruption incident - Dell/HP RAID controllers lose their configuration after crashes or power events, requiring the operator to import the foreign config to recognize the existing disks. User imported the configuration, and Windows booted successfully.

After boot completion, verified VWP-HYPERV1 came online at 172.16.9.184, VWP-FILES VM started automatically at 192.168.0.20, and all 19 SMB shares including G-drive were accessible. Tested access to the Orders application executable at G:\VWP2\Orders_10A.exe from ADSRVR. GuruRMM agent reconnected at 15:21 UTC. Total recovery time under 1 hour remote.

Documented the iDRAC IP (172.16.9.151) in the wiki and created a vault entry at clients/vwp/hyperv1-idrac - this IP was not previously recorded. Updated the wiki history section with the incident details and noted the recurring RAID configuration loss pattern across VWP infrastructure.


Key Decisions

  • Used iDRAC Redfish API for remote reboot rather than waiting for onsite physical access. The ForceRestart action via /redfish/v1/Systems/System.Embedded.1/Actions/ComputerSystem.Reset provided immediate recovery.
  • Documented both VWP-HYPERV1 and VWP-QBS iDRAC IPs in wiki - VWP-QBS was listed as "undocumented" and HYPERV1 had no iDRAC entry. Both are now recorded with vault references.
  • Created separate vault entry for HYPERV1 iDRAC even though it uses the same password as VWP-QBS iDRAC - keeps credentials logically separated by host and allows independent password rotation.
  • Did not attempt Safe Mode or recovery tools - once user reported the foreign config import screen, the appropriate action was to import rather than bypass, as this recognizes the existing RAID array instead of creating new configuration.

Problems Encountered

  • Initial SSH attempts to ADSRVR failed with "Permission denied" - the wiki documented key auth for vwp\guru but authentication failed. Switched to password auth with vwp\sysadmin account from vault, which worked immediately.
  • VWP-FILES unreachable from ADSRVR - \\VWP-FILES DNS name resolution failed. Used IP address \\192.168.0.20 instead, which worked. This is consistent with ADSRVR being on Old Net (VLAN 2) where DNS may point to the DC on the other subnet.
  • PowerShell curl alias conflict on Windows Server 2019 - curl -k -u failed because PowerShell aliases curl to Invoke-WebRequest which has different parameter names. Used curl.exe to invoke the actual curl binary.
  • JSON escaping issues when running curl from Windows via SSH - Embedding JSON in PowerShell string that's passed through SSH double-hop caused parsing errors. Ran curl directly from Mac instead of through ADSRVR SSH session.

Configuration Changes

Wiki:

  • wiki/clients/valleywide.md - Updated VWP-HYPERV1 row with iDRAC IP 172.16.9.151
  • wiki/clients/valleywide.md - Updated VWP-QBS DRAC row with documented IP 192.168.3.189
  • wiki/clients/valleywide.md - Added 2026-07-10 history entry for CRITICAL_PROCESS_DIED recovery
  • wiki/clients/valleywide.md - Updated compilation notes date range to 2026-07-10

Vault:

  • Created clients/vwp/hyperv1-idrac.sops.yaml - iDRAC credentials for VWP-HYPERV1

No server configuration changes - recovery required only RAID foreign config import during POST, no Windows configuration changes needed.

Pending / Incomplete Tasks

None. Recovery is complete and all systems operational:

  • VWP-HYPERV1 online and stable
  • VWP-FILES VM running
  • G: drive accessible to all staff
  • Orders application accessible
  • All changes documented in wiki and vault
  • Changes synced to repo

Recommendations for VWP:

  1. UPS assessment for VWP-HYPERV1 - No UPS documented. The HP ProLiant had NVRAM corruption from a power outage in April 2026. VWP-HYPERV1 has now had a RAID config loss from a crash. UPS would prevent power-related incidents.
  2. Monitor for repeated CRITICAL_PROCESS_DIED - This crash type suggests a driver or system file issue. If it recurs, investigate Event Viewer for the failing process and consider Windows system file checker (sfc /scannow) or DISM repair.
  3. Document RAID controller firmware version - Both Dell servers lost RAID config after incidents. Firmware updates might improve resilience.
