The following resources are necessary to install AdvancedCopy Manager on a Linux version PRIMECLUSTER:
Takeover IP address for AdvancedCopy Manager
Allocate a new IP address that is unique in the network for use in cluster system operations.
Fujitsu recommends preparing and adding a new logical IP address for AdvancedCopy Manager.
When allocating a new IP address, check whether existing transactions use the IP address as a takeover resource, and make sure that adding the corresponding GLS resource has no adverse effect on transactions. To use an existing logical IP address, make sure that sharing the logical IP address with AdvancedCopy Manager does not cause a problem (ie, a restriction) in existing products that already use the logical IP address.
Partition where shared data for AdvancedCopy Manager is stored
Prepare partitions on the shared disks on which to store shared data. The table below lists the number of required partitions. Note that the listed values indicate the number of partitions required for every transaction.
For more information about the size of the shared disks for shared data, see "3.2 Capacity of a shared disk".
Name | Storage Management Server transaction | Storage Server transaction |
Shared disk for AdvancedCopy Manager repository | 4 or 3 or 2 or 1 or 0 | 0 |
Shared disk for AdvancedCopy Manager shared data | 1 | 1 |
Total number of partitions | 5 or 4 or 3 or 2 or 1 | 1 |
Each of the partitions of the shared disk for the repository is used for the database area stored in the following four directories:
The directory for database file (This can be created on the shared disk for shared data.)
The directory for RDB dictionary (This can be created on the shared disk for shared data.)
The directory for RDB log file (This can be created on the shared disk for shared data.)
The directory for repository data storage database space (This can be created on the shared disk for shared data.)
Note
Define the shared disk for shared data and that for the repository as the shared disk used by PRIMECLUSTER.
Assign a disk that is not backed up or replicated using AdvancedCopy Manager as the shared disk for shared data and the shared disk for the repository.
The four directories can be created on the same shared disk that includes both the shared disk for the repository and the shared disk for shared data. However, in consideration of replicability and to upgrade performance, Fujitsu recommends each directory be created in a separate partition.
The shared disk for shared data and the shared disk for the repository are used for file systems. Make arrangements so that these disks can be mounted.
For information on how to set up the PRIMECLUSTER shared disk and file system, see the "PRIMECLUSTER Installation and Administration Guide."
Register the file system (the shared disk for shared data or the DB file system) as an Fsystem resource by following the procedure provided in 4.4.2 Customization Procedure. Follow the instructions in the "PRIMECLUSTER Installation and Administration Guide."
