S400, unloading the old network attached storage NAS and mounting the new network attached storage NAS.
Alternatively, different operating systems may be implemented differently for off-loading and on-loading network attached storage, as the invention is not limited in this regard.
For example, for offloading the old network attached storage NAS, the implementation of the present invention is as follows: 1. AIX is unloaded by using rmnfsmnt mode; 2. linux and HPUX then use the umount command and use regular expressions to process the "/etc/fstab" file. Where "/etc/fstab" is a file used to store static information about the file system, when the system is started, the system automatically reads information from this file and automatically mounts the file system specified in this file to the specified directory. Unloading a certain file system must process the "/etc/fstab" file, i.e. delete the information of the file system in the file, and the deletion will not be carried out at system start-up.
That is, in connection with the embodiment shown in fig. 1, in some alternative embodiments, the S400 includes: step 4.1, step 4.2 and step 4.3;
step 4.1, unloading the old network attached storage NAS;
step 4.2, deleting information in the file corresponding to the preset path;
optionally, after unloading the old network attached storage NAS, the present invention may first confirm with the system environment whether the new network attached storage NAS is mountable. That is, the present invention can confirm with engineers responsible for hardware and network maintenance whether the new network attached storage NAS is mountable, and of course, the network attached storage is a dedicated data storage server, belonging to hardware devices. The invention can also confirm whether a new network attached storage NAS can be mounted by first confirming whether the network attached storage has been allocated at the hardware level and then pinging the network attached storage for connectivity of the network IP address.
And 4.3, mounting the new network attached storage NAS, and adding corresponding information into the file corresponding to the preset path.
For another example, different operating systems are different in implementation manners for mounting and unloading network attached storage, and the main implementation manners are as follows: 1. AIX uses mknfsmnt mode to mount default parameters, and for data pump and heartbeat disk related type parameters, adopts modification "/etc/filesystems" file to implement; 2. linux and HPUX then use mount commands to modify the "/etc/fstab" file to implement default parameters, data pump parameters, and heartbeat disk parameters.
