Can anyone explain me how to create HTI pools in VSP G1000.
We are using this pools for Replication between our sites.
Help me out.
Thanks in advance.
HTI pool is just only differential data save in the local replication. If you want to replicate data between sites,
Consider remote replication such as truecopy or hur.
Thanks for the reply Jeon.I just want to confirm that HTI pool is nothing but a HDP pool right, or is it something different.
It is different between HDP pool and HTI pool.
HDP pool is thin or thick provisioning pool for making some v-vols used by HOST.
I want to correct my comment.
Not thin or thick provisioning pool but dynamic provisioning pool for thin or thick v-vols.
You are asking for an explanation as to how to create a Hitachi Thin Image (HTI) Pool. The procedures for these will be available in the supplied HTI User Guide "ThinImageUserGuide-RD80116.pdf"
You then mention creation of replication between sites.
HTI is used for internal replication only and not for any remote replication. HTI uses the HTI Pool to maintain differential data between P-Vol and the HTI S-Vols (V-Vols) when you have taken snapshot HTI Pairs. It is not used for any other purpose.
For replication between sites you need to configure Hitachi Truecopy (TC) or Hitachi Universal Replicator (HUR) or both if you are performing a multiple data center configuration.
HUR being an asynchronous replication model will use HUR Journal Pools as well - so I suspect perhaps this is the replication you are after seeing as you mention Pools and remote replication? In which case detail for configuring these can be found in "UniversalReplicatorUserGuide-RD80237.pdf"
Hope this helps.
You can create the pool either
- use storage navigator and create a pool
- or use raidcom add pool (make sure to specify it as a snap pool)
- You can also create it from device manager (Resources tab of HCS)
- You can also create it from Replication Manager.
Preferred is the last two methods. TI and HDP are different pools.
Just to let you know that while using HCS tool for creation of HTI pool, no such pool type option is found, however i could easily create it using Storage Navigator.
Kindly refer below screenshot for the same.
Not sure if it works in that way only.
