Hello,

Would you please help resolving IOS000I error message we are getting while running INIT on z1091 Version 1-3.43.20 build data 3.9.2012?

Here is the I/O error message we get when running an INIT on any devices defined to the NAS box.  We have not seen any I/O error for devices in the Linux internal storage.

IOS000I 0B11,EF,CMD,05,0E40,,00000000,ATS074,IBMUSERQ, 936       
 80000000C6000001000000210000170402008B4D43160F04000000E200000000

IOS000I 0B25,EF,CMD,05,0E40,,00C80000,ATS094,IBMUSER , 544       
 80000000C6C80001000000210000170402008B4D43160F04000000E20000C800

In general, when we defined a new CKD volume, we used the following command:

alcckd /mnt/NAS/DASD/ATS074 -d3390-3  (This is allocating the file to the NAS attach device)

alcckd /z/ATS074 -d3390-3 (This is allocating the file to the internal storage in the Linux box)

All of our I/O errors only occurs for volumes defined to /mnt/NAS/DASD directory.  All volumes define to /z never have an I/O error.

/z:

[ibmsys1@localhost ~]$ cd /z
[ibmsys1@localhost z]$ ls
