DELL PowerStore – WebUI (UI) unavailable after node reboots or power cycle of an appliance

DELL PowerStore – WebUI (UI) unavailable after node reboots or power cycle of an appliance 

is few months ago, when i prepared the two identical DELL PowerStore storage arrays, now the customer power it UP and suddenly the WebUI (UI) not working on PowerStore A and PowerStore B. We had a luck, that Management Cluster IP works and i was able to connect via SSH and Service account. 

 

!!! BOTH POWERSTOREs are not in PRODUCTION !!! 

 

PowerStore Manager UI or CLI (RestAPI and PSTCLI) is not available and may return the following errors:

  • PowerStore Manager UI is not accessible (users cannot log in) after an NDU, node reboot or, appliance power cycle:
  • Attempting to log in fails with error: „Service unavailable. Please retry in a few minutes. (0xE04040010004)“ or „503 Service Unavailable“
  • If going through the Initial Configuration Wizard (ICW) using the service port, the user may see a message saying „Loading….“ On the Cluster Details step which continues for a time. Eventually the UI may display „The required appliance was not found or Request timed out.“


As a result of this issue:

  • For unconfigured appliances
    • Impossible to access the PowerStore Manager login page or login into the REST API.
    • Connection Utility cannot show configured and unconfigured appliances in such environment due to absence of discovery IP on appliances.
  • For configured appliances
    • Impossible to access the PowerStore Manager login page or login into the REST API.
    • Add Appliance operation is not possible.

Resolution, which helped me

  • verify disc0 has an IPv4 address in the range of 169.254.0.0/16
  • reboot the peer node 
  • restart controlpath 

 

[SVC:service@XXXXXXX-A user]$ ip a show | grep disc0 -A 3
11: disc0@eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether aa:aa:aa:aa:aa:aa brd ff:ff:ff:ff:ff:ff
    inet6 fe80::18df:bcff:fe34:2b4a/64 scope link
       valid_lft forever preferred_lft forever
 
[SVC:service@XXXXXXX-B user]$ ip a show | grep disc0 -A 3
11: disc0@eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether bb:bb:bb:bb:bb:bb brd ff:ff:ff:ff:ff:ff
    inet6 fe80::18df:bcff:fe34:2b4a/64 scope link
       valid_lft forever preferred_lft forever

[SVC:service@XXXXXXX-B user]$ svc_node restart peer
[SVC:service@XXXXXXX-B user]$ svc_node status
Network Connectivity Status: OFF
Chassis PowerStatus: OFF
[SVC:service@XXXXXXX-B user]$ svc_node status
Network Connectivity Status: ON
Chassis PowerStatus: ON
[SVC:service@XXXXXXX-B user]$ svc_container_mgmt restart CP
Container controlpath restart returned: 0
Container controlpath is back up
Waiting for stack to load
Waiting for stack to load
Waiting for stack to load


Now is WebUI (UI)  back and accessible on the Management Cluster IP

Fix:
This issue has been fixed in the PowerStoreOS v3.6.0.0
(See the MDT-498676 listed in the release note for this operating system version.)
