Radoslaw,
I'm not an EMC CE, but since it appears that the DS,QD,xxxx,RDC appears to be 
asking the device what it supports, this is the indicator that MIDAW is 
disabled on the hardware side, so you probably need to contact your EMC support 
folks.

Subject: Two questions about MIDAW

The following scenario: z9, z/OS 1.7 with up-to-date service. FICON 
connections.

1. What steps should be done to enable MIDAW on non-IBM storage?
The box is EMC DMX3 with proper microcode level. AFAIK MIDAW support has 
to be enabled by EMC CE.
I wonder about activities on host side.




2. z9, z/OS 1.7 (with service), Shark ESS 800 with Microcode 2.4.4.112.

D IOS,MIDAW
IOS097I 10.41.07 MIDAW FACILITY 542
MIDAW FACILITY IS ENABLED

MVS command:
D M=DEV(8D10)
…
SCP TOKEN NED     = 002105.000.IBM.75.0000000xxxxx.0D00
SCP DEVICE NED    = 002105.000.IBM.75.0000000xxxxx.0D10
PAV BASE AND ALIASES  4
FUNCTIONS ENABLED = MIDAW

shows that MIDAV is enabled

But another Command show that is still *unavailable*:

DS,QD,8D10,RDC
UNIT VOLSER SCUTYPE DEVTYPE   CYL  SSID SCU-SERIAL DEV-SERIAL EF-CHK
8D10 ZXXXXX 2105800 2105000  3339  8D00 0175-XXXXX 0175-XXXXX **OK**
   READ DEVICE CHARACTERISTIC
2105E833900A5E80 BFF720240D0B000F E000E5A205940222 1309067400000000
0000000000000000 24241B02DFEE0001 0677080F007F4800 0035000000000000

X'80' means (in ...A5E80) means that MIDAW is disabled.
Q2: Is the microcode level correct for MIDAW?
Q3: If yes, what should be done to enable this function?
