In the following example, all access to application data is failing. The data set resides on a device managed by the soft partitioning feature of Solaris Volume Manager (SVM). Everything is failing with an I/O error.
df: (/data-84) not a block device, directory or mounted resource
cp: cannot create /data-84: I/O error
When you look at underlying device with metastat, you will discover a layered metadevice. d84 is a soft partition created from d80 which in turn is created from disk slice c0t12d0s0. This creation technique is not in line with best practices in
<Document 1417827.1> Solaris Volume Manager (SVM): Best Practices for Creation and Implementation of Soft Partitions
but none the less allowed. (d84 could be created directly from c0t12d0s0). This adds an extra layer of complexity to the problem at hand.
