NOTE: The use of link-local network addresses for defining CEPA servers is not supported. = time to scan each CEPA server. The default is 10 seconds and the range is 1 through 3600 seconds. The global ft option has three parts: ● level = fault tolerance level assigned. This option is required. Valid values are 0 through 3, where: ○ 0 = continue and tolerate lost events (default) ○ 1 = continue and use a persistence file as a circular event buffer for lost events ○ 2 = continue and use a persistence file as a circular event buffer for lost events until the buffer is filled and then stop CIFS/NFS ○ 3 = upon heartbeat loss of connectivity, stop CIFS/NFS ● location = directory where the persistence buffer file resides relative to the root of a file system. If a location is not specified, the default location is the root of the file system. NOTE: The file system that contains the persistence buffer file must have an amount of free space available equal to the maximum size of the persistence buffer file. For example, if the persistence buffer file size is 100 MB, the file system must contain at least 100 MB of free space for the temporary file operations. ● size = maximum size in MB of the persistence buffer file. The default is 1 MB and the range is 1 MB to 100 MB. = name assigned to the user account that the EMC CAVA service is running under on the CEE machine. For example, if the EMC CAVA service is running under a user called user1, the cepp.conf file entry would be msrpcuser=user1. If user1 is a member of a domain, the entry would be msrpcuser=domain\user1. = name assigned to the set of Windows Servers where the CEE software is installed. The specified Data Mover will use the set of servers to perform round-robin load sharing of events. One pool name must be specified. For only, you can specify up to three pool names, each on a separate line with an IP address. Refer to The cepp.conf file for an example. = IP addresses of the Windows Servers where the CEE software is installed, or an FQDN. NOTE: If you use an FQDN and the Data Mover cannot retrieve the IP address of it, add the FQDN to the /.etc/hosts list in the Data Mover. At least one Windows Server must be specified. Use the vertical bar (|) or a colon (:) when listing multiple addresses. NOTE: IPv6 addresses should be enclosed in square brackets to separate them from the colon delimiter that is used between multiple addresses. = events to receive notification of. You must define at least one error option line (pre, post, or posterr) from the following options: * (all events), blank (no events), OpenFileNoAccess, OpenFileRead, OpenFileReadOffline, OpenFileWrite, OpenFileWriteOffline, OpenDir, FileRead, FileWrite, CreateFile, CreateDir, DeleteFile, DeleteDir, CloseModified, CloseUnmodified, CloseDir, RenameFile, RenameDir, SetAclFile, SetAclDir, SetSecFile, SetSecDir. Use the vertical bar (|) when listing multiple events. The following table provides descriptions for these event options. ignore = if CEPA server is not available, ignore, and return no error to the caller. denied = if CEPA server is not available, return access denied to the caller. The caller will lose read/write access to the CIFS share. = timeout in millisecond (ms) to send a request that allows access to the CEPA server. Wait to receive the response from the CEPA server. The default is 1,000 ms and the range is 500 ms through 5,000 ms. = timeout in ms to retry the access request sent to the CEPA server. This value must be less than or equal to the reqtimeout value. The default is 250 ms and the range is 50 ms through 5,000 ms. Table 14.

NOTE:
The use of link-local network addresses for defining CEPA servers is not supported.
<surveytime>
= time to scan each CEPA server. The default is 10 seconds and the range is 1 through 3600 seconds.
The global
ft
option has three parts:
●
level
= fault tolerance level assigned. This option is required. Valid values are 0 through 3, where:
○
0 = continue and tolerate lost events (default)
○
1 = continue and use a persistence file as a circular event buffer for lost events
○
2 = continue and use a persistence file as a circular event buffer for lost events until the buffer is filled and then stop
CIFS/NFS
○
3 = upon heartbeat loss of connectivity, stop CIFS/NFS
●
location
= directory where the persistence buffer file resides relative to the root of a file system. If a location is not
specified, the default location is the root of the file system.
NOTE:
The file system that contains the persistence buffer file must have an amount of free space available equal
to the maximum size of the persistence buffer file. For example, if the persistence buffer file size is 100 MB, the file
system must contain at least 100 MB of free space for the temporary file operations.
●
size
= maximum size in MB of the persistence buffer file. The default is 1 MB and the range is 1 MB to 100 MB.
<msrpcuser>
= name assigned to the user account that the EMC CAVA service is running under on the CEE machine.
For example, if the EMC CAVA service is running under a user called
user1
, the
cepp.conf
file entry would be
msrpcuser=user1
. If user1 is a member of a domain, the entry would be
msrpcuser=domain\user1
.
<poolname>
= name assigned to the set of Windows Servers where the CEE software is installed. The specified Data
Mover will use the set of servers to perform round-robin load sharing of events. One pool name must be specified. For
<postevents> only, you can specify up to three pool names, each on a separate line with an IP address. Refer to
The
cepp.conf file
for an example.
<IP_addrx>
= IP addresses of the Windows Servers where the CEE software is installed, or an FQDN.
NOTE:
If you use an FQDN and the Data Mover cannot retrieve the IP address of it, add the FQDN to the /.etc/hosts
list in the Data Mover.
At least one Windows Server must be specified. Use the vertical bar (|) or a colon (:) when listing multiple addresses.
NOTE:
IPv6 addresses should be enclosed in square brackets to separate them from the colon delimiter that is used
between multiple addresses.
<eventx>
= events to receive notification of. You must define at least one error option line (pre, post, or posterr) from the
following options: * (all events), blank (no events),

table provides descriptions for these event options.
ignore
= if CEPA server is not available, ignore, and return no error to the caller.
denied
= if CEPA server is not available, return access denied to the caller. The caller will lose read/write access to the CIFS
share.
<reqtimeout>
= timeout in millisecond (ms) to send a request that allows access to the CEPA server. Wait to receive the
response from the CEPA server. The default is 1,000 ms and the range is 500 ms through 5,000 ms.
<retrytimeout>
= timeout in ms to retry the access request sent to the CEPA server. This value must be less than or equal to
the
reqtimeout
value. The default is 250 ms and the range is 50 ms through 5,000 ms.
