112 Troubleshooting NAS Blade systems that include external arrays

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

blocked.

Figure 63

Error occurs on the path to the external array used for node 1

1.

Restore (for example, check the cable’s connection status or change the switch) the status of the error

path between the local array and external array 1.

2.

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.)

” on

page 100.

3.

Perform a forced stop operation using NAS Blade Manager for resource group 1, which displays the

status as an srmd executable error.

4.

Stop node 1 using NAS Blade Manager.

5.

Restart NAS OS 1 (NAS channel adapter’s OS) using LUN Manager or NAS Blade Manager.

6.

Start node 1 using NAS Blade Manager.

7.

To release the blocked status of node 2’s file system, perform the following operations:
a. Change resource group 2’s execution node to node 1 using NAS Blade Manager (failover).
b. Restart NAS OS 2 (NAS channel adapter’s) using LUN Manager or NAS Blade Manager.
c. Change resource group 2’s execution node to node 2 (failback).

8.

Start resource group 1 on node 1 using NAS Blade Manager.

If both nodes use the same external array

In the configuration in

Figure 64

, all of the NAS Blade system’s user LUs are volumes in the external

array. Only one external array is connected to the local array. Also, only one path is set between the

local array and external array. In this case, if an error occurs in the only set path, none of the volumes in

the external array can be used.
