PowerScale OneFS 9.8.0.0 Backup and Recovery Guide

Verify the 2x10GbE + 2x8GB Fibre Channel NIC connectivity

1. Verify that the 2x10GbE + 2x8GB Fibre Channel NIC cards are available:

   # ls /dev/ocs*

   The output should show ocs0 and ocs1.

2. Verify that the cluster Fibre Channel connectivity and zoning are accurate by matching the Fibre Channel WWPNs output displayed with the WWPNs displayed in the DMA user interface:

   # isi fc settings ls

   In the following sample output, the WWPNs should match the ones displayed in the DMA:

   Port  WWNN             WWPN            State Topology Rate

   2.1  200000109b12b5ce 100000109b12b5ec enable  nport      8 
   2.2  200000109b12b5cd 100000109b12b5ed enable  nport      8

   3.2  200000109b12b611 100000109b12b611 enable  nport      8 
   4.1  200000109b12b0b8 100000109b12b0b8 enable  nport      8 
   4.2  200000109b12b0b9 100000109b12b0b9 enable  none     auto

3. Detect NDMP backup devices:

   # isi tape rescan --reconcile

   A sample output of the previous command is shown:

4. Verify that zoned devices are visible and accessible, and that the NICs in the same zone have multiple paths. The following is an example of the command on tape04:

   isi tape view tape041 
   

   The output is similar to the following:

   Name: tape041
