Still a draft work in progress


This is a capture page to identify potential real hardware or software generated examples that can help test Rollback Quality Improvements.
This is also a capture page for a missing scenarios list that could have been overlooked in previous versions of CoprHD. The goal is to make CoprHD more resilient to external changes done outside.
 

Environment changes

PlatformExternal change triggered
VMAX
VMAXFA ports in port groups are rebalanced, more ports are added outside of CoprHD
VMAXCoprHD created Storage group/Initiator group/Port group is renamed
VMAXCoprHD created Storage group/Initiator group/Port group is deleted
VMAXCoprHD created masking view is renamed.
Example: Changed to NO_VIPR, so none can delete it.
VMAXPre-existing Storage group/Initiator group/Port group ahead of CoprHD workflows.
Elements already in a group with same name as CoprHD created or populated into a different name 
VMAXVolumes removed from CoprHD created Storage groups.
Mismatches are triggered, with CoprHD thinking this is the last volume in SG.
VMAXCreate storage groups with invalid characters allowed by Solutions Enabler CLI,
but unable to be parsed by SMI-S (COP-25791)
VMAXExpand CoprHD created volume outside.
VMAXRe-installed SMI-S provider. SYMAPI database deleted.
VMAXGrowing storage groups(addition or removal of device) external to CoprHD

VMAXVolume created in CoprHD but Export/ un-export happens without CoprHD knowledge
VMAXChanging over utilized ports to new ports
VMAX

Changing host I/O limits externally on ViPR created storage group and subsequent change vpool.

VMAXVMAX SRDF group itself is deleted or the mode changed to Adaptive/Asynchronous/Synchronous outside of CoprHD
VMAXHaving RDF groups with single letter "A" on the VMAX array
VMAXConfiguration lock applied at the service processor outside of CoprHD on the array itself.
VMAX

Create devices outside of CoprHD with same device_label names, and execute delete operations

VNXSAN Copy session created outside. Snapshot mount point configured for this LUN outside.
VNXProvider is re-installed with all of the VipR CGs gone. Provider remsys/addsys for VNX array executed outside.
Unity

Outside of CoprHD, an ignore initiator in the host initiator properties is applied.Once an initiator is ignored, the host can no longer access storage from it

Symptoms and Error messages

CoprHD Error messages What does this error message actually mean ?
 
Operation failed due to the following error: Smis job failed: Invalid lun, exceeds maximum allowed value
HLU value entered for host exports exceeds the value 4095
Error 16001: Unable to contact the SMIS provider. Unable to call SMIS provider successfully.
Caused by: The requested object cannot be found.

Refresh the provider in CoprHD and retry.
Restarting the provider is another option before retry.
