To create a new pair
Note: The below options are used for the instance, IH[#] for TC, and IM[#] for for SI
- -IH[#] or -ITC[#] Set to HORC mode [and HORCMINST#]
- -IM[#] or -ISI[#] Set to MRCF mode [and HORCMINST#]
# For SI
paircreate -g vsp-9985v_rpt1-si -vl -IM14 11
# For TC
paircreate -g VSP_test1 -vl -f async -jp 01 -js 01 -IH10 1
# For COW
paircreate -g vsp-rpt1-cow -vl -pid 2 -IM14
Options are
- -v option
- -vl is working on the local system
- -vr is working on the remote system
- -f async – is for to use async insted of sync
- -jp & -js – used for the local & remote jurnal group, one jernal group per consistency group
- -IM – SI instance name
- -IH – TC instance name
- Consistency group
- For COW
- -pid is the COW-SSD pool id
Note: Make sure to change the inflow control to no on the jernal group, what it dose is explained below.
Notes on HUR
[u]CWP[/u]: Link between sites and the amount of data that is being replicated can cause potential performance impact. If huge amounts of data is being replicated causing a congestion, then it may cause "Cache Write Pending" to go high. High sustained CWPs over 33% will cause the host IO shutdown and the data will be destaged to backend disk as a priority. Even the pairs may be suspended as their may not be enough cache to cope with the load. So first thing I would check is if there were any spikes at the time of replication using Tuning Manager.
[u]HUR Inflow Control[/u]: You need to set this option carefully based on the environment. Below are the definitions.
The HUR ?Inflow Control? parameter allows a reduction in the number of I/Os which the storage subsystem receives by delaying the response to the host I/Os (in other words, whether to slow or delay response to hosts). This function can restrict any data overflow from the journal volume
Yes indicates inflow will be restricted.
No indicates inflow will not be restricted.
Having Inflow control set to ON effectively can cause perceived performance issues to the host.
[u]HUR Line of Speed setting[/u]:
When using Universal Replicator software with low bandwidth between the production and recovery sites, you may have to change the Speed of Line parameter to a lower value to avoid potential pair suspension. The value should be set to be equal to or less than the available telecommunication bandwidth between sites.
To split a pair
To split temporarily so the S-vol lun can be used
# For SI
pairsplit -g 9985v-test-si -IM14
# For TC
pairsplit -g 9985v-test-tc -IH10
To split permanent. (delete the pair)
# For SI
pairsplit -S -g 9985v-test-si -IM14
# For TC
pairsplit -S -g 9985v-test-tc -IH10
To re-sync the spit volume
# For SI
pairresync -g 9985v-test-si -IM14
# For TC
pairresync -g 9985v-test-tc -IH10
To switch P-vol and S-vol
# For TC
horctakeover -g VSP_test1 -IH1
# For SI
horctakeover -g si_test1 -IM1
return lun (hex) status
# Gives lun numbers in hex, the way it should be
raidscan -p CL3-A -fx
raidscan -p CL3-A -CLI
To configure DeviceManager on each host
# /opt/HDVM/HBaseAgent/agent/config/server.properties
server.server.serverIPAddress=hcs (chnage to none qfdn)
server.agent.rm.centralizePairConfiguration=enable
/opt/HDVM/HBaseAgent/bin/hdvmagt_account (to set login / password, HaUser/haset)
#To report in to hcs as an agent
/opt/HDVM/HBaseAgent/bin/HiScan -s hcs
To get a lun block size
raidcom get ldev -ldev_id 70 -IM3
