Cirrus Data Cloud VM Lookup And Assignment

This file covers vCenter VM lookup responses and the workflow for assigning existing disks and PCI passthrough FC adapters to a VM.

Cluster Scope Rule

• Only work under cluster QACL-ATVMCypressONLY unless explicitly told otherwise.

Ignore VMs

• vCLS-bf0ec6f6-c7e2-4383-b11e-9c97cec7ed44
• vCLS-e5b3c60e-6a1c-46a6-8357-191fc0ab8e14

IP Lookup Rule

• If asked about an IP address, only check powered-on VMs.

VM Lookup Response Rule

• Unless the user explicitly asks otherwise, return VM lookup/list results only from cluster QACL-ATVMCypressONLY.
• For vCenter VM lookup requests, always report:
• VM name
• datastore name
• VM notes/annotation
• include power state and IP when available

VM Disk And FC Assignment Workflow

• When asked to assign existing disks and PCI passthrough FC adapters to a specified VM, treat the request as a two-step workflow:
• first gather and report findings
• then wait for explicit approval before making any changes
• Always log into vCenter 192.168.0.201.
• Find the specified VM and verify the ESXi host it is currently running on.
• If the requested VM name is not present exactly as given, search for the closest live inventory name and report the mismatch before planning any change.
• Default expected ESXi host is 192.168.1.165, but always verify live placement before planning changes.
• Always identify and report the datastore where the VM is stored before planning disk attachment.
• Unless the operator explicitly specifies alternatives, default to these PCI passthrough FC adapters:
• vmhba7 (0000:85:00.0)
• vmhba8 (0000:85:00.1)
• Do not substitute any other PCI FC passthrough adapters if either default or operator-specified adapter cannot be found.
• Unless the operator explicitly specifies alternatives, default to these existing disks from the VM's datastore under the atvm-DISKS directory:
• atvm-DISK_1.vmdk
• atvm-DISK_2.vmdk
• Do not substitute any other disks if either default or operator-specified disk cannot be found.
• If the specified adapters or specified disks cannot be found, do nothing and report that nothing will be assigned.
• For these requests, never substitute a different datastore directory when atvm-DISKS is missing.
• Before any assignment action, always provide a summary of:
• the VM found
• any name mismatch between requested VM name and live inventory VM name
• the ESXi host
• the datastore
• whether vmhba7 and vmhba8 were found and are usable
• whether atvm-DISK_1.vmdk and atvm-DISK_2.vmdk were found under atvm-DISKS
• exactly what would be assigned
• Never perform the assignment step until the operator explicitly approves after seeing that summary.

Common VM Credentials

• Source /home/aw/code/cds/.env.credentials.local
• Linux username: ATVM_TARGET_USER
• Linux password: ATVM_TARGET_PASSWORD
• Windows username: ATVM_WINDOWS_TARGET_USER
• Windows password: ATVM_WINDOWS_TARGET_PASSWORD

Status Output Format (Power-Off/Revert/Power-On)

• VM [vm name] was poweredOn, so I powered it off (or already poweredOff)
• Snapshot rollback completed
• VM [vm name] powered back on successfully
• Current IP: <ip>
