This section describes the additional query and list outputs within an O-MDM migration.
The following list output displays a new flag column showing if the session is a SAN (O-MDM) migration session:
symdm -sid 644 list
Symmetrix ID : 000197900644
Total
Flg Source Target Capacity Done
Storage Group OS Array Array State (GB) (%)
---------------------- -- ---------------- ------------ -------------- --------- ----
APP1 XX APM00150519204 000197900644 CutoverSync 100.7 100
APP2 X. 000197100643 000197900644 Migrating 8.0 90
Legend:
Flags:
(O)ffline X = Offline, . = N/A
(S)AN X = SAN, . = N/A
If the -sg option is given, the new SAN flag will be shown as a new field below the SG name:
symdm list -sid 643 -sg APP1
Symmetrix ID : 000197100643
Storage Group: APP1

If the Migration State is MigrateFailed, the Source WWN Status (Error Code) field will be one of the following different values:
In addition, the Last Error Timestamp will note (format example, Thu Sep 19 07:03:12 2019) when the error was encountered for that specific source WWN – target device pair.
