Hi All,
Could you please tell me from where the MIH values will be taken?
Is there any member other than IECIOSxx member in Parmlib?
Reason I'm asking is, in IECIOSxx I saw the below settings:
MIH DASD=00:45
MIH DEV=(700-70F),TIME=10:00
MIH DEV=(7D0-7D3),TIME=45:00
But when I display the MIH settings, I saw the below output:
-D IOS,MIH
IOS086I 09.07.36 MIH AND IOT TIMES 208
MOUNTMSG = NO, HALT=00:05, MNTS=03:00, UREC=03:
DASD=00:45, TAPE=03:00, GRAF=03:00, CTC =03:00, COMM=03:
CHAR=03:00, IOTDASD=00:00, IOTTAPE=00:00,
US02=00:15 UDEV=E000, E001, E002, E003, E004, E005, E006
E008, E009, E00A, E00B, E00C, E00D, E00E
Eventhough the tape value is not defined in IECIOSxx member, the TAPE value is set as 3mins. I don't know from where it is picking.
If anybody knows about this, please help.
Thank you.

Hi Enrico,
Thank you, for your response.
I have one more doubt.
In IECIOSxx the parameters are like this:
MIH DASD=00:45
MIH DEV=(700-70F),TIME=10:00
MIH DEV=(7D0-7D3),TIME=45:00
But when I display its showing different DEV which is not defined in IECIOSxx parm
-D IOS,MIH
IOS086I 09.07.36 MIH AND IOT TIMES 208
MOUNTMSG = NO, HALT=00:05, MNTS=03:00, UREC=03:
DASD=00:45, TAPE=03:00, GRAF=03:00, CTC =03:00, COMM=03:
CHAR=03:00, IOTDASD=00:00, IOTTAPE=00:00,
US02=00:15 UDEV=E000, E001, E002, E003, E004, E005, E006
E008, E009, E00A, E00B, E00C, E00D, E00E
Can you please tell me on this?
Thank you.

You mean: Here is exactly the same question, can you now answer it, because I don't know what "googling" is!

First, these are the types of questions that you absolutely MUST talk to your site support group about -- a forum can suggest but since we don't work at your site, we don't have any absolute answers for you.
Second, I suggest that the IECIOSxx member you THINK is being used may not be getting used -- it is possible to have more than one PARMLIB for providing the parameters, you know. Many sites use an IBM library for the values provided during installation, plus a customization library that has site-specific parameters, plus (often) a SYS1.PARMLIB for the classic parameters. That could explain the discrepancy in unit addresses.
Third, if you read the MVS Initialization and Tuning Reference manual you can find out that MIH TAPE has a default value of 3:00 minutes and hence it is not being picked from anywhere -- that is the usual value if not elsewhere specified.

Hello,
I feel that 3:00 minutes is the default value.
If you look here www.ibm.com/support/knowledgecenter/SSLTBW_2.1.0/com.ibm.zos.v2r1.ieam900/m012949.htm
Note: Just noticed that the link is for z/OS 2.2, you might want to look up the same link for your OS version for the defaults.
link says
Code:
IOS086I hh.mm.ss MIH & IOT TIMES
MOUNTMSG = YES, HALT=00:05, MNTS=03:00, UREC=03:00,
DASD=00:15, TAPE=03:00, GRAF=03:00, CTC =03:00, COMM=03:00,
CHAR=03:00, IOTDASD=00:00
US01=00:05 UDEV= 0420, 0421, 0422, 0423, 0424, 0425, 0426, 0427,
0428, 0429, 042A, 042B, 042C, 042D, 042E, 042F,
US02=00:11 UDEV= 0420, 0421, 0422, 0423, 0424, 0425, 0426, 0427,
0428, 0429, 042A, 042B, 042C, 042D, 042E, 042F,
US03=00:00 UDEV= 0490, 0491, 0492, 0493.

In this example, the installation used the IBM® supplied defaults for all device classes.
This default setting output looks a lot similar to your output except the DASD=00:45 & that is probably you have MIH DASD=00:45 on the PARMLIB member.

Do you have MOUNTMSG=NO in your parmlib member?
Your output shows MOUNTMSG=NO, but the IBM default for z/OS 2.2 is MOUNTMSG=YES.
If there is no MOUNTMSG in your parmlib member then we can say for sure that the parms are being picked up from a different parmlib member.

we are all wasting time here...
if the TS had clicked on the link I provided and scrolled down a couple of pages
he would not have had the need to ask ...
