We have running server with attached SAN storage and everything was fine. However last week we moved our server blade to a new chassis. Everything is same, we just add new WWN in Brocade SAN switch to allow access of storage, but my server isn't able to see the SAN disk in fdisk output.

I'm seeing the following output just wondering what is wrong?

[root@server1 ~]# dmesg | grep qla

Two LOOPs? Is that OK?

EDIT #1:

I've added the following WWN in Brocade SAN switch for zoning:

[root@server1 ~]# systool -c fc_host -v | grep port_name
    port_name           = "0x2100001b329df4a9"
    port_name           = "0x2101001b32bdf4a9"

What is node_name?

[root@server1 ~]# systool -c fc_host -v | grep -e port_name -e node_name
    node_name           = "0x2000001b329df4a9"
    port_name           = "0x2100001b329df4a9"
    node_name           = "0x2001001b32bdf4a9"
    port_name           = "0x2101001b32bdf4a9"
  • You've got two ports, so that doesn't look strange. Make sure you got the right WWN for the port you zoned. – Mat Jan 5 '14 at 15:25
  • I have correct WWN in SAN switch systool -c fc_host -v | grep port_name – Satish Jan 5 '14 at 15:40
  • I have edit my question and put more info – Satish Jan 5 '14 at 15:42
  • You've talked about zoning, but not lun masking. Did you update that too? – Mat Jan 5 '14 at 17:44
  • I have checked on EMC storage side and its saying partially active connection status? Do i need to re-register it? – Satish Jan 6 '14 at 16:17

Finally problem resolved

  1. shutdown server
  2. de-register node in Unisphere console
  3. start server
  4. Add node in Storage group again
  5. run powermt config
  6. Voila!!!
