Failure phenomenon:
AIX is connected to the front of the Vnx, and storage Group,aix is configured on each channel on the array without assigning a lunz device.
(Visible using LSDEV-CC disk), causing LUN space to not be used properly.
Solution:
1. To configure Storage group/storage View and add Hlu 0, you must manua

A common programming problem:
Which one is faster than traversing arrays and linked lists of the same size?According to the algorithm analysis method in university textbooks, you will conclude that these two are as fast as they are because the time complexity is O (n ). However, in practice, the two are very different. The following analysis shows that arrays are much faster than linked lists.
First, we will introduce a concept: Memory Hierarchy (storage
