Normaly in a truecopy replication state we see different codes telling us teh health of the pairs. Here are the most common ones.

We discussed about HiCommand and that the default user account is system with the password of "manager"... However, that is not very secure so we are looking to add new users and grant them permission on different components. However, we could take advantage of LDAP authentication so we can enable HDS to peform LDAP queries to AD. This way, users ...

Here is another great document (given a bit old from a how-to perspective) that HDS put together to explain the main differences between ShadowCopy and CopyOnWrite Insystem replication http://www.hds.com/groups/public/documents/webasset/system-replication.html?M=insystem-replication-demo

A LUN may be used with any device which supports read/write operations, such as a tape drive, but is most often used ...

As noted in the previous post regarding HiCommandCLI installation you need to specify the url, username and password every time you need to run a command (think of it more of passing a command to hicommand device manager server). There is a way to automate that server and specify only the action that you want to take. What needs to ...

Device Manager has a command line as well. It can be downloaded and installed locally on any machine or it can be lunched from the default hdvm (hicommand device manager) installation directory (usually drive:\Program Files(x86)\HiCommand\) under the DeviceManager\HiCommandCLI folder. It's main application it's a batch file called hicommandcli.bat. Please note that Java JRE is required for this tool. HicommandCLI - ...
