The CCI components on the storage systems include the user data volumes and CCI command devices.

    (for example, for online maintenance), you can switch to an alternate command device manually.

Therefore, one or more alternate command devices (see Alternate command device function on page...

CCI has TWO phases that it reads to acquire usable LBA, and writes with the acquired LBA in attaching sequence to the command device, so the command device can confirm whether it was required as the assignment for CCI or not, by detecting and adding two status bits to the instance assignment table.

  • Page 37: Issuing Commands For Ldevs Within A Luse Device

    Issuing commands for LDEVs within a LUSE device A LUSE device is a group of LDEVs regarded as a single logical unit. Because it is necessary to know the configuration of the LDEVs when issuing a command, a new command is used to specify a target LU and acquire LDEV configuration data, as shown in the following figure.

  • Page 38: Cci Instance Configurations

    Figure 2-8 HORCM operational environment CCI instance configurations The basic unit of the CCI software structure is the CCI instance. A CCI instance consists of HORC manager (HORCM), CCI commands, the user- defined configuration definition file, and the log function for maintenance. Each instance uses its own configuration definition file to manage volume relationships while maintaining awareness of the other CCI instances.
  • Page 39 Figure 2-9 CCI instance configuration & components The four possible CCI instance configurations are: • One host connected to one storage system. Connecting one host to one storage system allows you to maintain multiple copies of your data for testing purposes or as an offline backup. Each CCI instance has its own operation manager, server software, and scripts and commands, and each CCI instance communicates independently with the command device.

  • Page 40: Host Machines That Can Be Paired

    storage systems in different geographic areas. Each CCI instance has its own operation manager, server software, and scripts and commands, and each CCI instance communicates independently with the command device. Each RAID storage system has a command device that communicates with each CCI instance independently. Each storage system contains the primary volumes of its connected CCI instance and the secondary volumes of the other CCI instance (located on the same host in this case).

  • Page 41: Configuration Definition File

    Restriction: CCI's communications among different operating systems is supported on HP-UX, Solaris, AIX, Linux, and Windows (this is not supported on Tru64 UNIX/Digital UNIX). Also, CCI does not require that the HORCMFCTBL environment variable be set—except for RM-H and RM-S instances (to ensure that the behavior of the operating system platform is consistent across different operating systems).

    Notes: Use decimal notation for numeric values (not hexadecimal). For VSP G1000, G1500, and VSP F1500, add a “3” at the beginning of the serial number. For example, for serial number 12345, enter 312345. Do not edit the configuration definition file while CCI is running. Shut down CCI, edit the configuration file as needed, and then restart CCI.

    System configuration using CCI This section describes system configurations using the in-band method or out-of-band method. In addition, a system configuration for connecting to an in-band CCI server by using the out-of-band method is also described. For an overview of the in-band and out-of-band methods, see Command execution by the in-band and out-of-band methods on page 1-5.

    System configuration for connecting to a CCI server connected by the in-band method using the out-of-band method In the out-of-band method, CCI server ports can be specified as virtual command devices. Specifying a CCI server port as a virtual command device allows you to use the out-of-band method to connect to a CCI server connected to a storage system using the in-band method.

    system in In-Band method can be connected in Out-of-Band method. If a CCI server is specified as a virtual command device, it provides better performance than the Out-of-Band method with specified SVP/GUM as a virtual command device. Hardware requirements CCI uses SCSI path through driver to issue I/O for command device. To use CCI server port as virtual command device, the virtual command device interface needs to be converted to the actual SCSI path through interface.

    The global storage virtualization function enables you to minimize rewrites of configuration definition files (horcm*.conf) when you operate volumes migrated from older models to the VSP G1000, VSP G1500, VSP F1500, VSP Gx00 models, or VSP Fx00 models. You can also minimize the modification of the script file that you used for the older models, when you operate volumes using the script file created by you.

  • Page 304: Group Version Control For Mixed Storage System Configurations

    Group version control for mixed storage system configurations Before executing each option of a command, CCI checks the facility version of the storage system internally to verify that the same version is installed on mixed storage system configuration. If the configuration includes older storage systems (for example, 9900V), this method might not meet the requirements for the mixed storage system environment, because the older storage system limits the availability enhancements in later facility versions.
