110 Troubleshooting NAS Blade systems that include external arrays

• When resource group 2’s status is Offline, start resource group 2.

14.

Change the error disk in the external array to restore the external array’s status.

15.

Execute the Check Paths & Restore Vol. command using External Storage XP. For instructions, see

Checking the connection status and resuming external LU operations (Check Paths & Restore Vol.)

page 100.

16.

Perform the following operations on node 1 and node 2:
a. Set up the differential-data storage device using NAS Sync Image.
b. Create the file system, and create the NFS share and CIFS share using NAS Blade Manager.

Errors in a path to the external array

Figure 62

shows an example of when an error occurs in a path between the local array and an external

array. In

Figure 62

, an error occurs in the path between the local array and external array 1; however,

the path between the local array and external array 2 is normal.
The situation in

Figure 62

is as follows:

Clients cannot access volumes in external array 1, but can access volumes in external array 2.

The local array recognizes that the status of all file systems and volumes in external array 1 are

blocked.
