How to Replace Battery on RAID SE5310/SE5320

Solution

DISPATCH INSTRUCTIONS

- WHAT SKILLS DOES THE ENGINEER NEED:
Technician should have a clear understanding of RAID and replacing RAID hardware. Also NAS 5000 knowledge and understanding.

- TIME ESTIMATE: 60 minutes

- TASK COMPLEXITY: 2

DISPATCH INSTRUCTIONS

FIELD ENGINEER INSTRUCTIONS:
- PROBLEM OVERVIEW:

what: NAS cache battery

where: < Chassis S/N: , Slot No. of the card/device to be inserted here by SR owner>

why: cache not functioning; batteries expired; re-enable cache
- WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE
RESOLUTION ACTIVITY?:

This can be done while the system is on line but it is recommended that an outage be taken. NAS should be taken down or offline.

- WHAT ACTION DOES THE ENGINEER NEED TO TAKE:
Type in CLI

load lsi_menu

*note in using the 'lsi_menu' If you keep depressing a key while it is waiting to perform an action it will kick you out of the menu.

Wait until it completes before hitting another key. Key in lsi_menu to get back in.
To get to the telnet menu key in menu in the telnet command line
If possible open two telnet windows one to run the lsi_menu and one to restore the LUN Paths.
If the LUN paths are not restored after the RAID Controller is replace, it is possible to cause a reboot or disruption to the use of the NAS if it does not have a proper path to failover. 2
The steps required to replace the battery are in the order shown
See figures below to see how to perform the steps
1. Check to see that all of the LUN Paths are 'OK'
2. If this is a Clustered head performed step 1 on the partner's head
3. If not 'OK' either restore or set the LUN Paths
4. If this is a Clustered head performed step 3 on the partner's head
5. Load lsi_menu
6. Set one controller offline (B)
7. Remove the offline controller (B)
8. Replace the battery on controller B
9. Insert the RAID controller back to its slot
10. Set the controller to online (B)
11. Restore the LUN Paths to 'OK'
12. If this is a Clustered head performed step 11 on the partner's head
13. Set the second controller offline (A)
14. Remove the offline controller (A)
15. Replace the battery on controller A
16. Insert the RAID controller back to its slot
17. Exit the lsi_menu
18. Key in menu to get to the telnet menu
19. Restore the LUN Paths to 'OK' (shown on the figures below)
20. If this is a Clustered head performed step 19 on the partner's head
21. Reset the batteries dates
22. Check that the cache is enable
23. Exit the lsi_menu
24. Unload the lsi_menu <unload lsi_menu>
25. Get a diagnostic email

ESC for Menu
Notice that the isp1 and isp6 alternate and the OK on the last columns
The isps are the HBAs in this case hba1 and hba6
And the options 1. Restore and 2. Auto-assign. Always use restore to restore
Not auto-assign unless it is the first time this is done
When the controller is placed offline the HBA will failover to the other HBA
And should be restore after replacing each controller
