InterSystems IRIS Installation custom layout structure

#InterSystems IRIS

Hello Respected members,

I am new with InterSystems IRIS , want to setup the environment on RHEL 7.5 with multiple lun layouts (separate LVM for DB , Journal, and WIJ), 

I would like to get some help in setting up the same, as far as I know, the installation will go through on a single directory ( I did not see any option to chose path/directory for DB's or WIJ /journals), hence after installation I would like to move my DB's to separate LVM and WIJ on another LVM set

Please suggest or share the steps for the  same document if any for the same, that will be really helpful, Thanks

 

Regards

RS

1. Install InterSystems IRIS.

2. Shut it down.

3. Open <iris>/iris.cpf, there you will find:

[Databases]
USER=C:\InterSystems\IRIS\Mgr\user\

[Journal]
AlternateDirectory=C:\InterSystems\IRIS\Mgr\journal\
CurrentDirectory=C:\InterSystems\IRIS\Mgr\journal\

[config]
wijdir=C:\InterSystems\IRIS\Mgr\WIJ

4. Edit this file as you wish and move the corresponding directories.

5. Start InterSystems IRIS.

@Eduard Lebedyuk 
Thank you so much for providing this information

I would like to know if I can move only user database or default databases as well??

Like 

irislib, irisaudit, irislocaldata and other under mgr folder 

Please suggest if I can do this if yes then what sort of permission do I need to change for new directory path and what all files I need to copy at new location??

I want to setup my layout as given below

  • Database LUNs = 8 x 512GB- - - > vg_iris_db
  • Journal LUNs = 2 x 512GB - - > vg_iris_jrn
  • WIJ LUNs = 2 x 256GB - - > vg_iris_wij
  • Install and IRISTEMP LUNs = 2 x 128GB - - - > vg_iris_sys

Please suggest if modification in iris.cpf file can do this all operation 

Thanks & Regards

All databases can be moved

what sort of permission do I need to change for new directory path

irisusr should have RW access to the folder. The easiest way is to check what access (owner, group, permissions) is set for existing files/folders and then recreate the same in a new location.

and what all files I need to copy at new location??

IRIS.DAT and stream subfolder if it exist.

Please suggest if modification in iris.cpf file can do this all operation  

Absolutely.

@Eduard Lebedyuk 

Thank you so much for providing the detailed information.

I am able to deploy the IRIS Instance with custom layout which I wanted to 

One thing I noticed that after installation I was able to see the instance running from command line but I was unable to access management portal with the URL that comes after installation, anything I missed or need to change to make it accessible?

Please suggest 

Thanks

Hello Rahul - I didn't see your new post yet but this message is pretty clear. The problem is at the OS level in resolving the hostname, scsps2391082001. If you replace the hostname in your URL with the actual IP of your server, it should work fine. If you want the hostname to work, I'd work with your OS/networking team to set that up.

Hello Rahul,

I'd check your messages.log to see messages regarding the private webserver. Then I'd check the OS to see if anything is holding your configured web server port.

This could be worth a new post, or contacting the WRC.

Thank you all for providing the inputs for my queries
