DASD STATUS - F-NRD
Hallo To all, I put a dasd address offline. But when I display the status it shows the following: D U,,,933E,1 IEE457I 06.55.23 UNIT STATUS 109 UNIT TYPE STATUSVOLSER VOLSTATE 933E 3390 F-NRD/RSDNT The explanation for F says that the device is offline, however, when I look at the NRD explanation it says that the device is not ready, which I am not sure what it implies . My question is the drive offline and safe to initialize or do I have check something else?

Re: DASD STATUS - F-NRD
Is the drive offline, F-NRD on all LPARs? If yes, you're ready to init the volume.

Re: DASD STATUS - F-NRD
Yes, it shows the status (F-NRD) on the 3 lpars. What concerns me is that doesn't show the desired OFFLINE status. O'Brien, David W.

As you stated earlier, 'explanation for F says that the device is offline'. What more do you want?

Re: DASD STATUS - F-NRD
John, David is correct. You can initialize the volume. The F-NRD is the status that I normally see.

Re: DASD STATUS - F-NRD
I am just trying to understand why the NRD is displayed. When I look at other devices the status is OFFLINE. My concern is why the status doesn't go to OFFLINE instead of staying at F-NRD.

Re: DASD STATUS - F-NRD
Here is my 2 cents worth. The only issue here is whether or not the device is offline. If there is an F it is offline. I believe the NRD is a throw back to the old days when you could flip a switch that would READY or NOT READY the physical drive. That is no longer valid with RAID, Shark and others of this ilk. There are times when you will really see OFFLINE and other times you will see F-NRD. Both are acceptable to indicate a device is Offline. If I am wrong, please feel free to correct - especially you dinos out there. Is the NRD a throwback or some other indicator.

In a message dated 10/27/2006 9:07:17 A.M. Central Daylight Time, [EMAIL PROTECTED] writes: The only issue here is whether or not the device is offline. If there is an F it is offline. Correct. The DISPLAY command was written decades ago when drives could really be not ready, is attempting to display as much info as possible, and uses the F as an abbreviation to allow room for more info, such as NRD. IBM apparently did not want to rewrite that part of the code just because it was no longer possible for DASD drives to become not ready. There is a large number of different reasons why IOS will not issue a Start Subchannel instruction to a DASD, and not ready was one of them long ago and in a galaxy far away. There is still a bit in the UCB for this condition. It does not occur on DASD anymore, but can occur on other device types (tape drives, e.g., on which you can still mount a new volume). I believe the NRD is a throw back to the old days when you could flip a switch that would READY or NOT READY the physical drive. Correct. There are probably still some DASD error recovery situations in which IOS uses this bit as a quick and dirty way to render a device unstartable. There is also a bit in the IOSB that a caller of STARTIO can turn on to tell IOS to do the SSCH even if the UCB says the device is not ready. If I am wrong, please feel free to correct - especially you dinos out there. You are not wrong. Bill pre-Cambrian Fairchild Facts are the enemy of truth.
