References: 

N/A

Issue Description: 

Customers and Field Service Representatives that install X-option add-on
IDE disk drives or who are replacing an existing Ultra 5 or Ultra 10 disk
drive FRU, will encounter the following error when attempting to use the
format utility from the systems console:
	
# format

Searching for disks...WARNING: /pci@1f,0/pci@1,1/ide@3/dad@1,0 (dad1):         
        corrupt label - wrong magic number

WARNING: /pci@1f,0/pci@1,1/ide@3/dad@1,0 (dad1):
        corrupt label - wrong magic number
        

NOTE* Example screen output only. The number of messages will vary depend-
      ing upon how many devices without labels have been installed.
	 
	
Upon further investigation, it has become evident that NEW x-option and 
FRU IDE disk drives are un-labeled.

Corrective Action: 

Customers and Field Service Representatives that encounter the problem
of "corrupt label - wrong magic number" after installing add-on X-opton
IDE disk drives OR who replaces an existing IDE disk drive FRU, are 
prompted to perform the following workaround:

1.  After an IDE disk drive FRU or x-option IDE add-on drive has been
    installed in the system (Ultra 5 or Ultra 10), follow the routine
    service procedure to boot the system.

2.  Invoke the "format utility" and observe the following:

    *Example screen output for ONE IDE disk drive added to the system.
     
    # format

     Searching for disks...WARNING: /pci@1f,0/pci@1,1/ide@X/dad@X,0 (dadX):
     corrupt label - wrong magic number

     WARNING: /pci@1f,0/pci@1,1/ide@3/dad@X,0 (dadX):
     corrupt label - wrong magic number
        

    AVAILABLE DISK SELECTIONS:

       0. c0t1d0 
          /pci@1f,0/pci@1,1/ide@X/dad@X,X

      *1. c0t1d0 
          /pci@1f,0/pci@1,1/ide@3/dad@X,0

    Specify disk (enter its number): 1

	 
3.  Then select the disk number appropriately, *in this case disk 1 is the
    newly connected disk.
	

    Selecting c0t1d0
    No defect list found
    [disk formatted, no defect list found]

        quit
format> label



4.  Select the option "label" to label the selected drive.

    Ready to label disk, continue? y

5.  Confirm "y" for the above question.

    *After "y" is specified a NEW label will be written to the drive.

6.  At the "format" prompt enter quit.

    format> quit

7.  Now that the IDE disk drive has been labeled follow routine service
    procedures to partition the disk drive.

		
*The next time that the "format utility" is invoked, the "corrupt label-
 wrong magic number" should not be evident if the IDE disk drive has been
 labeled correctly.

Comments: 

Beginning May 1, 1998, all Ultra 5 and Ultra 10 hard drive x-options
will arrive from the factory pre-formatted, pre-partitioned, and pre-
labeled, and it will no longer be necessary to follow the above
instructions for partitioning, and labeling.
