Preserve Mirror reason codes

When ANTRQST returns to the caller, and the RETINFO return and reason code are zero, and the ANTQFRVL header return code is zero, and Version 2 or higher is specified, each volume entry has one of the values described below.
Preserve Mirror Capable Preserve Mirror Reason Description
1 0 (X'00') The volume is Preserve Mirror Capable.
2 0 (X'00') Preserve Mirror checking not requested.
3 0 (X'00') Preserve Mirror checking was not done because the volume is not FlashCopy capable.
0 . The volume is not currently Preserve Mirror capable. The volume reason will have a non-zero value indicating the current cause for being incapable.
0 1 (X'01') The maximum number of FlashCopy relations are active on the volume.
0 2 (X'02') Reserved
0 3 (X'03') Reserved
0 4 (X'04') The volume's secondary is a Concurrent Copy source.
0 5 (X'05') The volume's secondary is an XRC primary.
0 6 (X'06') The volume's secondary currently is inhibited from starting any FlashCopy operations.
0 7 (X'07') A Volume Level (Phase 1) FlashCopy relation is active on this volume's secondary.
0 8 (X'08') The maximum number of FlashCopy relations for the volume's secondary volume's SFI.
0 9 (X'09') The volume's secondary is inaccessible.
0 10 (X'0A') The volume's secondary is a Global Mirror primary.
0 11 (X'0B') A full volume target relationship already exists in the volume's secondary.
0 12 (X'0C') A full volume source relationship already exists on the volume's secondary and target capability was requested.
0 13 (X'0D') The maximum number of full volume source relationships exist on the volume's secondary and source capability was requested.
0 14 (X'0E') The volume's secondary is space efficient.
0 15 (X'0F') The volume's secondary is in the process of a PPRC cascading failover/failback recovery or the PPRC volume was established with incremental resync. Target capability is required.
0 16 (X'10') The volume's secondary is a cascaded PPRC volume.
0 17 (X'11') The volume's secondary is not capable of dataset-evel FlashCopy operations,
0 18 (X'12') The volume's secondary is not capable of inhibiting writes to the source.
0 19-127 (X'13-1B') Reserved
0 128 (X'80') The volume is not a PPRC primary device. For target checking, software can treat this as capable.
0 129 (X'81') The volume's secondary and the control volume's secondary are not in the same SFI.
0 130 (X'82') The volume's PPRC relationship is not full duplex.
0 131 (X'83') The volume's secondary's SFI does not have the microcode installed that supports IBM Remote Pair FlashCopy (Preserve Mirror).
0 132 (X'84') The control volume is not a PPRC primary.
0 133 (X'85') The command was received while the subsystem was installing a new microcode load and the level of one or both CECs does not support IBM Remote Pair FlashCopy (Preserve Mirror).
0 134 (X'86') An error was detected when sending the command to the volume's secondary.
0 135 (X'87') The volume is space efficient and target capability was requested. Space efficient volumes are not allowed as the target of a Preserve Mirror operation.
0 208 (X'D0') The volume is a PPRC primary and the Preserve Mirror feature is not enabled.
0 209 (X'D1') PPRC Primary not Full Duplex or Preserve Mirror version 2 not installed.
0 256 (X'100') The controller does not have the Preserve Mirror feature enabled.
