Command

Argument

Description

 

syncparams

-r/--remoteip < remote ipaddress >

Syncparams is used to sync the

 

syncreplica

-x/--xmlflag

iscsi base target names/date and

 

 

 

time between local and remote

 

 

For example:

machines before creating an HA

 

 

 

pair.

 

 

syncparams -r 172.16.70.148 syncreplica

This command has to be executed

 

 

in the Primary machine before

 

 

 

 

 

 

creating the first RG between two

 

 

 

iTX machine.

 

 

 

 

 

managerg syncreplica

-t/--type <action{create/delete/get/editalias/

Managerg command is used to

 

 

removealias/addalias/changeowner/forcetakeover}>

manage and configure Resource

 

 

-n/--rgname <resource group name>

Group. Action denotes the

 

 

-a/--alias <Alias>

operation to be perfomed on the

 

 

-r/--remoteip <remote ipaddress>

RG

 

 

-v/--vipaddress <Virtual iapddress>

 

 

 

-l/--local <localipaddress>

This command is also used to

 

 

-f/--force

add/remove/edit virtual IP

 

 

-x/--xmlflag

configured for a specific RG.

 

 

 

Note: Atleast one VIP should be

 

 

For example:

present for an RG.

 

 

managerg -t create -n rg0 -a Alias-1 -a Alias-2 -r

 

 

 

172.16.70.146 -l 172.16.70.176 syncreplica

This command is also used the

 

 

managerg -t get syncreplica

change the original ownership of

 

 

managerg -t delete -n rg0 syncreplica

an RG.

 

 

managerg -t editalias -n rg0 -v 172.16.70.10 -a

 

 

 

Alias-1 syncreplica

 

 

 

managerg -t addalias -n rg0 -a Alias-2 syncreplica

--forcetakeover option can be used

 

 

managerg -t removealias -n rg0 -a Alias-2

to takeover the RG forcefully if the

 

 

syncreplica

RG is in an inconsistent state but

 

 

managerg -t changeowner -n rg0 syncreplica

this may result in data corruption.

 

 

managerg -t forcetakeover -n rg0 syncreplica

 

 

 

 

--force option is used to delete an

 

 

 

non operational RG forcefully if

 

 

 

remote is dead.

 

create syncreplica

–l/--local < cont_vol_name>

Creates a replication pair. Both the

 

 

-r/--remote < cont_vol_name>

primary and secondary volumes

 

 

-p/--priority <resync priority>

should be present before this

 

 

-i/--localhost <primary's IP address>

operation.

 

 

-m/--remotehost <rem host name>

Default resync priority is 25.

 

 

-d/--mode [hanodsm]

Specify sync for –d/--mode option

 

 

-g/--rgname <resource group name>

pair; specify hanodsm for –d/--

 

 

Example: HA NO DSM replication in remote

mode option to create an high-

 

 

volumes

availability pair.

 

 

create -l c0_v0 -r c1_v1 -p 50 -i 172.16.70.70 -d
