When using AdvancedCopy Manager's manager and agent in an IPv4/IPv6 addresses coexisting environment, the following combinations are possible.
Management Server's IP Address Environment | Managed Server's IP Address Environment | ||
|---|---|---|---|
IPv4 | IPv6 | IPv4/IPv6 | |
IPv4 | A (Connect with IPv4) | N/A | A (Connect with IPv4) |
IPv6 | N/A | A (Connect with IPv6) | A (Connect with IPv6) |
IPv4/IPv6 | A (Connect with IPv4) | A (Connect with IPv6) | A (Connect with IPv4/IPv6(*1)) |
A: available; N/A: not available
*1: Connect with either IPv4 or IPv6 (IP address that the user registered on AdvancedCopy Manager).
Point
If both IPv4 and IPv6 format IP addresses are set to the operating system and AdvancedCopy Manager in the Management Server, a Managed Server with IPv4 address and a Managed Server with IPv6 address can be managed by one Management Server.
Refer to "stgxfwcmmodsrv" for information on setting method for IPv4 and IPv6 format IP addresses to AdvancedCopy Manager.
This product supports IPv6 from version 15.3. For this reason, the Management Server connects to the Managed Server with an IPv4 address if the version of the AdvancedCopy Manager's agent is 15.2 or earlier even if the Managed Server OS supports operations using an IPv6 address.
Note
Since communication fails between a Managed Server with IPv4 and a Managed Server with IPv6, the following functions are not available in the IPv4/IPv6 addresses coexisting environment:
Inter-server replication between the Managed Server with IPv4 and the Managed Server with IPv6.
Management information batch backup with a Managed Server taken as a management information batch backup server.
Even if both IPv4 and IPv6 format IP addresses are set to the operating system, the IP address of a Managed Server allowed to be registered on AdvancedCopy Manager is either IPv4 or IPv6.
If a Managed Server with IPv4 IP address and a Managed Server with IPv6 IP address are registered on AdvancedCopy Manager with IPv6 address, the range in which communication is allowed is as follows:
