Getting started with Command View EVA

• Command View EVA
• Graphical user interface that controls and
  monitors the storage system
• Software that supports the GUI
• Each installation of Command View EVA on the SMA
  is a storage management agent
• The client for the agent is a standard Internet
  browser

  Properties page
• Agent Options Selects interface and management
  agent options
• Help Displays online help in a new window

Configuration process steps

• Gather preliminary information
• Develop a requirements list per server
• Create a list of all FCAs
• Determine the host WWN
• Perform a software code load (if necessary)
• Initialize the storage system
• Perform a disk drive firmware code load (if
  necessary)
• Create additional disk groups as desired
• Install and configure hosts
• Create the hosts
• Create the virtual disks
• Create snapshots and snapclones

13
Gathering preliminary information (1 of 3)

• Develop a requirements list per server
• Virtual disk characteristics
• Size (GB)
• Virtual RAID level (VRAID0, VRAID5, and VRAID1)
• Operating system LUN identifier (used for OpenVMS
  and Tru64 UNIX)
• Which virtual disks can share a disk group
• Create a list of all FCAs
• WWID of FCAs in the servers
• Which FC switch port
• Which server

14
Gathering preliminary information (2 of 3)

• Determine the host WWN
• OpenVMS (V7.21H1 or 7.3)
• Analyze/system
• SDAgt FC SHOW DEVICE FGA0 (FGB0, and so on.)
• Alpha SRM console
• SHOW DEVICE
• Windows NT/2000
• LPUTILNT (LightPulse Utility/NT)

15
Gathering preliminary information (3 of 3)

• Determining the host WWN
• Tru64 UNIX
• emxmgr (select 1)
• /var/adm/messages
• Alpha SRM console
• SHOW DEVICE
• SUN Solaris
• /var/adm/messages (only if adapter driver is
  loaded)
• IBM AIX
• lsconfig
• HP-UX
• fcmsutil or tdutil

16
Starting with the uninitialized storage system
17
Initializing the storage system (1 of 8)

• Creates a usable storage system
• Binds controllers as operational pair
• Establishes preliminary data structures on the
  disk array
• Creates the default disk group
• Only must be done first time you configure the
  storage system or if the storage system is
  uninitialized

18
Initializing the storage system (2 of 8)

• Three levels of EVA metadata
• Storage system-level quorum disks
• Holds controller information
• WWN
• Storage system name
• Character map of disk groups and virtual disk
  members, but not virtual disk chunk mappings
• Quorum disk requirements
• Minimum of two quorum disks to boot HSV
  controllers
• Minimum of five quorum disks
• Maximum of 16 quorum disks (1 per disk group)
• Storage requirements are pre-allocated at 0.03
  on each disk

19
Initializing the storage system (3 of 8)

• Disk group metadata
• Disk group characteristics
• Number of spindles
• Spare space allocation
• Virtual disk chunk mapping
• Command View EVA metadata
• The management logical disk (MLD) provides
  metadata for Command View EVA
• Devoted to the SMA
• Spread across metadata area on all disks in disk
  groups
• Holds backup copy of current controller
  configuration
• Holds SMA controller events and controller data
  such as trap host lists and license lists

Performing a disk drive firmware code load

• Loaded separately from VCS and EMU firmware
• Disk must not belong to a disk group
• Downloads disk drive firmware one disk drive at a
  time
• Files loaded from browser client
• Click Code Load on Disk Enclosure Bay Properties
  page

Viewing and changing disk group properties
32
Deleting disk groups

• Disk groups can be deleted through the Disk Group
  Properties page
• Click Delete
• Click OK to confirm your actions
• You cannot delete
• A disk group if it has virtual disks
• The default disk group unless an additional disk
  group has been created to protect metadata

33
Installing and configuring hosts

• Host installation required before creating hosts
  through the GUI
• Configuration process for all operation systems
• Uses OS platform kits
• Steps must be completed in order
• Step 6, Installing Multipathing Software, is only
  required for certain operating systems

34
Creating a host

• Collect host information
• LAN name
• IP address
• WWID of one FCA
• Operating system
• Create a host folder
• Add a host
• Add more FCAs
• Verify that the host has been added

43
Creating a virtual disk

• Create a virtual disk folder
• Create a virtual disk/virtual disk family
• Virtual disk family contains
• Only one active virtual disk
• One snapshot (if one exists)

44
Creating a virtual disk family (1 of 2)
Enter the name of the virtual disk
