afmAsyncDelay |
Seconds |
Indicates the time at which the requests start flushing to the secondary cluster. For
write-intensive applications that write to the same set of files, this delay is helpful because it
replaces multiple writes to the secondary cluster with a single write containing the latest data.
However, setting a very high value weakens the consistency of the data on the remote cluster. |
primary |
afmDisconnectTimeout |
Seconds |
Defines the interval until which the primary gateway waits after it detects that the
secondary cluster is inaccessible before declaring the outage by moving the primary cluster state to
Disconnected. |
primary |
afmEnableNFSSec |
- |
If enabled at primary, exported paths from secondary with kerberos-enabled security levels
like sys, krb5, krb5i,
krb5p are mounted at primary in the increasing order of security level -
sys, krb5, krb5i,
krb5p. For example, the security level of exported path is
krb5i then at primary, AFM tries to mount with level sys,
followed by krb5, and finally mounts with the security level
krb5i. If disabled at primary, exported paths from secondary are mounted with
security level sys at primary. You must configure KDC clients on all the
gateway nodes at primary before enabling this parameter. |
primary |
afmHashVersion |
|
Specifies the gateway node hashing algorithm that minimizes the impact of
gateway nodes joining or leaving the active cluster by running as few recoveries as possible and
balance mapping of AFM DR filesets across the gateway node. Valid values are 1,2,4, and 5. Default
value is 2. You can specify the value by using mmchconfig. For example, to set
the value 4, run mmchconfig afmHashVersion=4. |
Not applicable |
mountRetryInterval |
Seconds |
Specifies the interval after which the primary gateway retries an operation at secondary, in
cases where the secondary is in an unhealthy state. Needs the GW node recycle or -i
option for immediate effect. It is tunable per gateway. The updated value is visible only as long as
the gateway is active and is applicable for all filesets owned by that gateway. |
primary |
afmRPO |
Minutes, hours, weeks |
Specifies the interval for generating RPO snapshots. |
primary |
afmAsyncOpWaitTimeout |
seconds |
Specifies the time that AFM DR waits for completion of any inflight asynchronous operation
which is synchronizing with the primary. Subsequently, AFM DR cancels the operation and synchronizes
again after primary is available. |
primary |
afmSyncOpWaitTimeout |
seconds |
Specifies the time that AFM DR waits for completion of any inflight synchronous operation
which is synchronizing with the primary. When any application is performing any synchronous
operation at primary, AFM DR tries to get a response from primary. If primary is not responding,
application might be unresponsive. If operation does not complete in this timeout interval, AFM DR
cancels the operation. |
