Elastic Storage Server ver 3.0.4 Package Description - Advanced Edition

Elastic Storage Server (ESS) Advanced Edition ver 3.0.4 solution is 
composed of various components tested together for compatibility and 
correctness. Key components are RHEL, IBM Spectrum Scale RAID for ESS, 
and Power System Firmware.

     No changes from 3.0.2

  e) Updated firmware rpm to support new drives
     and updated enclosure firmware


2. Additional Information if upgrading from a version earlier than 3.0.2

      You must upgrade to ESS ver 3.0.4 level if your client nodes use an
      InfiniBand network to access ESS. Ver 3.0.4 (as well as version 3.0.2
      and 3.0.3) provides a more graceful handling of serious hardware faults
      generally triggered by overloaded Infiniband adapter and therefore better
      suited to protect client data from such hardware faults.

3. Known Issues in ver 3.0.4
   a) Issue: IBM Spectrum Scale filesystems (ver 4.1.0-8) fail to mount on
      RHEL 7.1 nodes due to a systemd issue

      Description: ESS 3.0.x contains IBM Spectrum Scale RAID ver 4.1.0-8
      which has a problem mounting on Red Hat Enterprise Linux  7.1 due an 
      issue with systemd.  Updating cluster nodes to the latest systemd
      packages will correct the issue.

      Affects: Cluster filesystem
      Type: Install or Upgrade
      Version: Advanced or Standard
      Affected Nodes: IO Server nodes and  EMS nodes

      Resolution or Action: To workaround this issue  do the following:
      - Connect your cluster nodes to the Red Hat network (RHN) and apply
        the RHBA-2015-0738 errata prior to mounting your GPFS filesystems.
      - If your unable to connect to the RHN directly you may download the
        required rpms and update them manually on each node or create a
        local yum repository.

      - The minimum required rpms and levels are:
        systemd-sysv-208-20.el7_1.2.ppc64.rpm
        systemd-libs-208-20.el7_1.2.ppc64.rpm
        systemd-208-20.el7_1.2.ppc64.rpm
        libgudev1-208-20.el7_1.2.ppc64.rpm
        The advisory can be found here:
        https://rhn.redhat.com/errata/RHBA-2015-0738.html

   b)  Issue: At very high load the ESS console log will show error messages
       from the mpt2sas driver (due to an issue in driver management of the
       PCC64 IOMMU).  This is only observed in systems configured with
       Infiniband network operating at a very high load.

       You may see messages similar to these in the console log.
          sd 5:0:19:0: pci_map_sg failed: request for 2105344 bytes!
          mpt2sas 000b:05:00.0: iommu_alloc failed,
                           tbl c000000f26929c00 vaddr c000002570954000 npages 8

       Resolution or Action: Reduce IO driver concurrency by reducing
         nsdMinWorkerThreads and nsdMaxWorkerThreads as a short term mitigation.
         IBM is working with partners investigating a more permanent resolution
         of this issue.

       Example:
       mmchconfig nsdMinWorkerThreads=1k,nsdMaxWorkerThreads=1k -N gss_ppc64
       Replace gss_ppc64 with ESS IO Server nodeclass (or IO Server node list)
       if your default ESS IO Server nodeclass has changed.

4.2 ESS 3.0.x is shipped with OFED level 

	MLNX_OFED_LINUX-2.4-1.0.2 (OFED-2.4-1.0.2) 

It is installed and upgraded as part of the GPFS Native RAID for 
ESS solution.  It is highly recommended not to install or update 
OFED outside the GPFS Native RAID for ESS solution. 


4.3 ESS IO Server Node System Firmware and IBM PCIe3 x8 Cache SAS RAID 
   Internal Adapter Firmware

IBM Power System S822L (8247-22L) is used as the IO Server Node and 
IBM Power System S821L (8247-21L) is used as Executive Management 
Server (EMS) node. The system firmware and RAID Internal Adapter 
Firmware is not expected to be upgraded in the field under normal 
operation. Following are the level of the system firmware and RAID 
internal adapter firmware. 

Item                             Firmware

4.4 Red Hat Enterprise Linux Level and update considerations

ESS 3.0.x supports Red Hat Enterprise Linux 7.1 
 kernel release:  3.10.0-229.el7.ppc64 

User can update RHEL as needed to address security updates. 
It is highly recommended to limit errata updates applied to the Red 
Hat Enterprise Linux  operating system used in the ESS solution to 
security errata or errata updates requested by service. For more 
information visit Red Hat's solution article on applying only 
security updates:  https://access.redhat.com/solutions/10021
