ost --update_client --name --mode Description Updates the attributes of an OST client (OST client name and mode). The OST client modes are auto, passthrough, and dedupe. If an OST client has four or more CPU cores, it is considered to be dedupe-capable. However, the OST client operating mode depends upon how it is configured in the DR Series system. • Auto - Sets the mode to dedupe or passthrough as determined by the media server. The mode used is based on how many cores the OST client has and whether it is 32-bit or 64-bit. If the OST client has four or more CPU cores, it will run in the dedupe mode. If the OST client has less than four CPU cores, it will run in passthrough mode. For details, see the table below. • Passthrough - The OST client passes all data to the DR Series system for dedupe processing. This is also known as "appliance-side dedupe". • Dedupe - The OST client processes hashing on the data. This is also known as "source-side dedupe" and is the default mode. Keep in mind that the OST client must be dedupe-capable (four or more CPU cores) in order for this mode to be in effect. If the OST client is not dedupe-capable, it will run in passthrough mode regardless of its dedupe mode setting. The following table shows the relationship between the configured OST client mode types and the supported client mode based on client architecture type and corresponding number of CPU cores. Table 2. Supported OST Client Modes and Settings OST Client Mode Settings Auto Dedupe Passthrough 32-Bit OST Client (4 or 64-Bit Client (4 or more CPU Cores) more CPU Cores) Passthrough Not Supported Supported Dedupe Supported Supported 32-Bit OST Client (Less than 4 CPU Cores) Passthrough Not Supported Supported 64-Bit OST Client (Less than 4 CPU Cores) Passthrough Not Supported Supported Syntax ost --update_client --name acme-81 --mode dedupe NOTE: You may be able to force writes for OST clients running in the Passthrough mode using the DR Series system CLI mode --dedupe command. The change in OST client mode is effective on the next backup operation when you are using Symantec NetBackup. (If you are using Symantec Backup Exec, you will need to restart this service for it to recognize that a new mode has been configured.) Result OST client updated successfully. ost --limit --speed

ost --update_client --name <OST Client Hostname> --mode <auto | passthrough | dedupe>
Description
Updates the attributes of an OST client (OST client name and mode). The OST client modes are
auto
,
passthrough
, and
dedupe
. If an OST client has four or more CPU cores, it is considered to be dedupe-capable. However, the OST client
operating mode depends upon how it is configured in the DR Series system.
•
Auto
— Sets the mode to
dedupe
or
passthrough
as determined by the media server. The mode used is based on
how many cores the OST client has and whether it is 32–bit or 64–bit. If the OST client has four or more CPU cores, it
will run in the
dedupe
mode. If the OST client has less than four CPU cores, it will run in
passthrough
mode. For
details, see the table below.
•
Passthrough
— The OST client passes all data to the DR Series system for dedupe processing. This is also known as
“appliance-side dedupe”.
•
Dedupe
— The OST client processes hashing on the data. This is also known as “source-side dedupe” and is the
default mode. Keep in mind that the OST client must be dedupe-capable (four or more CPU cores) in order for this
mode to be in effect. If the OST client is not dedupe-capable, it will run in
passthrough
mode regardless of its
dedupe
mode setting.
The following table shows the relationship between the configured OST client mode types and the supported client
mode based on client architecture type and corresponding number of CPU cores.

NOTE:
You may be able to force writes for OST clients running in the
Passthrough
mode using the DR Series
system CLI
mode --dedupe
command. The change in OST client mode is effective on the next backup operation
when you are using Symantec NetBackup. (If you are using Symantec Backup Exec, you will need to restart this
service for it to recognize that a new mode has been configured.)
Result
OST client updated successfully.
ost --limit --speed <<num><kbps | mbps | gbps | default> --target <ip address | hostname>
Description
Limits the bandwidth consumed by OST (OpenStorage Technology) for a system you define by IP address or hostname
(
--target
), by which you define the speed in kilobytes/second (KBps), megabytes/second (MBps), gigabytes/second
(GBps), or an unlimited bandwidth (default).
Syntax
ost --limit --speed 10mbps --target acmesys-49
