IBM SAN DS 3400 configuration

[nrayty]

Hi,

I am trying to rebuild a redhat 5.5 cluster system into Centos 6.4

At this stage, i am trying to understand the system before rebuild.

Encounter a problem in the IBM DS 3400 SAN configuration. Using smcli command the arrays and logical drives are fine.

But when i use


[master ~]# mmlsdisk gpfs0

disk driver sector failure holds holds storage
name type size group metadata data status availability pool
------------ -------- ------ ------- -------- ----- -------- ------------ ------------
nsd01 nsd 512 4001 yes yes ready down system
nsd02 nsd 512 4002 yes yes ready down system
nsd03 nsd 512 4003 yes yes ready up system
nsd04 nsd 512 4004 yes yes ready up system
nsd05 nsd 512 4005 yes yes ready up system


nsd01 and nsd02 availability are down.

Tired - mmnsddiscover -a -N all
and it returns - mmdsh: master-c00 remote shell process had return code 255.

Any ideas ?

Tks.
