D IOS,MIH - source ?

Post by aterechko » Sat Dec 17, 2016 11:39 pm

Hi MVS experts,

Below is results of execution D IOS,MIH command:

IOS086I 18.59.15 MIH AND IOT TIMES 462
MOUNTMSG = YES, HALT=00:05, MNTS=05:00, 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=00:30 UDEV=0A80, 0A81, 0A82, 0A83, 0A85, 0A86, 0A87, 0A88,

Who could tell me, which MVS control blocks contain the values of MOUNTMSG and MNTS ?

Thanks a lot in advance !

the values displayed are those set by the IECIOSxx member used
they are READ ONLY values used by the MIH to take the appropriate actions

the manual has the description of all the keywords and the default values
so no control block lurking is needed

if no IECIOSxx member was used the values shown are the default ones
( same effect as having a IECIOSxx member with the default vaules explicitly specified )


cheers

Hello Enrico,

Thanks a lot for your feedback.
I have to check these values in the code that enhances a tape management system.
Of course the program could read the IECIOSxx member or issue D IOS,MIH command and analyze
a reply from MIH but this way is not too intelligent and can in certain cases provide incorrect data.
Anyway there are must be control blocks which contain these values.

Cheers

Alex

Certainly -- but that does NOT mean that IBM has made knowledge of those particular control blocks public. If IBM has not published the data about them, then you're not going to be very successful at using them.
