Functions

func AddVolumesToRemoteSG

func AddVolumesToRemoteSG(ctx context.Context, remoteSymID string, pmaxClient pmax.Pmax) (bool, error)

AddVolumesToRemoteSG adds remote volumes to default SRP SG on remote array

func GetOrCreateMigrationEnvironment

func GetOrCreateMigrationEnvironment(ctx context.Context, localSymID, remoteSymID string, pmaxClient pmax.Pmax) (*types.MigrationEnv, error)

GetOrCreateMigrationEnvironment creates migration environment between array pair

func ListContains

func ListContains(a []string, x string) bool

ListContains return true if x is found in a[]

func ResetCache

func ResetCache()

ResetCache resets all the maps being used with migration

func StorageGroupCommit

func StorageGroupCommit(ctx context.Context, symID, action string, pmaxClient pmax.Pmax) (bool, error)

StorageGroupCommit does a "commit" on all the migration session SG Returns true if not sessions found, all migration completed

func StorageGroupMigration

func StorageGroupMigration(ctx context.Context, symID, remoteSymID, clusterPrefix string, pmaxClient pmax.Pmax) (bool, error)

StorageGroupMigration creates migration session for "no-srp" masking view storage groups 1. Remove volumes from default SRP SG 2. Create migration session for no-srp SG 3. Create default SRP storage group on remote array, and maintain a list of volumes to be added.
