1. There are 2 VNX5400 boxes in the storage domain (We call them VNXA and VNXB temporarily).
2. Domain master is VNX A. When customer logs into Unisphere by using VNX A IP address, VNX A file part showed grey out and VNX B worked fine.
3. After destroying and rebuilding domain on VNXA, everything works fine.
4. Then one manually adds VNXB to VNXA’s storage domain. Now VNXB’s file menus are shown grey out.
5. If one performs the rebuild action on VNXB again and adds VNXA to the storage domain of VNXB, VNXA’s file menus are shown grey out.
6. Destroy the domain on SPs for 2 VNXs by running domain destroy script. Still no work.
7. It is noticed that while domain master is VNXA, everything works fine when logging in Unisphere via SP’s IP of VNXB.
8. It has a Unisphere Warning alert like
Severity : Warning
System : vnx5300cs
Domain : Local
Created : Jul 25, 2017 8:14:19 AM
Message : Logging into xxx.xxx.xxx.xxx encountered an error.
Full Description : An error occurred during the login process. The control station did not log in properly.
Recommended Action : The login error may have occurred because: 1. Certificates are not accepted. 2. Both storage processors or the control station are not accessible. 3. You have logged in to a File or Block system using a local user account not defined on both the File and Block systems.
Event Code : 0xfffffffffffffff9
1. Both VNXA’s control station and VNXB’s control station have the same host name “VNX5400”.
2. Both VNXA’s array name and VNXB’s array name have the same array name “VNX5400”.
This is the root cause.
1.Change the hostname of VNXB’s control station (“VNX5400-117” as an example):
#nas_cs -set -hostname VNX5400-117
2.Change VNXB’s array name fromVNX5400 to VNX5400-117:
#/nas/sbin/navicli -h spa arrayname VNX5400-117
3. Reboot control station and issue is fixed.
To have more than 1 VNX array in the storage domain, please make sure control station’s host name and array’s name are unique across the domain.
