MSA1000 configuration problems

[Adel Elamin]

Dear John Kufrovich
today I went to the site and I did as you told me

CLI-1> show connections
Global_ris doesn't exist. No named connections exist.

Connection Name:
Host WWNN = 50014380-00C418BB
Host WWPN = 50014380-00C418BA
Profile Name = Default
Unit Offset = 0
Controller 1 Port 1 Status = Online
Controller 2 Port 1 Status = Offline

Connection Name:
Host WWNN = 50014380-00C418A1
Host WWPN = 50014380-00C418A0
Profile Name = Default
Unit Offset = 0
Controller 1 Port 1 Status = Offline
Controller 2 Port 1 Status = Online

CLI-1> set connection Unknown wwpn=50014380-00C418BA profile=Linux
Connection Unknown doesn't exist. No connection attributes are modified.


CLI-1> add connection app2-0 wwpn=50014380-00c418ba profile=linux
Cannot save any connection information because global_ris is NULL.



CLI-1> set globals rebuild_priority=medium system_name="msa-1" read_cache=50 write_cahche=50
Setting System Name to: 'msa-1'
Could not modify global parameters since no logical units exist!

Global Parameters:
System Name: msa-1
Rebuild Priority: low
Expand Priority: low

Cache is NOT configured - use 'set globals/unit' to configure cache!

Temperature:
No temperature sensor support.

CLI-1> show globals

Global Parameters:
System Name: msa-1
Rebuild Priority: low
Expand Priority: low

Cache is NOT configured - use 'set globals/unit' to configure cache!

Temperature:
No temperature sensor support.

=====================================

I did uninstall HBA old drivers form the server and install new version but still problem exists, when ever I reboot the server it will hang in initializing hardware till I remove one fiber connection
Please advice any help
Thanks

No global RIS means you lost all your Array configuration.

What were you doing when this occurred. Did you up date MSA FW?

[Uwe Zessin · Accepted solution]

This message also comes up on a new box - you need to create at least one "unit" (logical disk).

[Adel Elamin]

The problem has been solved, but I need an explanation for this

I only add one unit (logical drive) as you told me by using this command
add unit 0 data="disk101-disk102" raid_level=0

as soon as I did that and I reboot the servers, the servers never hang again as well as the logical drive on the MSA appear in the severs and the ACU can detect the MSA controller

I need an explanation for that before I close this thread
Thanks Uwe Zessin, John Kufrovich, and Ganesh Chichakar
I'm really glad for your support and I hope to hear form you again
