Introduction
Use the following instructions to connect your host and cluster to InfiniBox.
Zoning
Follow these guidelines:
Host readiness
The following instructions specify how to configure an Oracle VM Server host connected to InfiniBox.
Connect to the server using the following command. Provide the root password.
ssh root@server-name
Create a backup version of the multipathing configuration file:
cp /etc/multipath.conf /etc/multipath.conf.bak
Create a new multipathing configuration file:
vi /etc/multipath.conf
The content of the file should be:
devices { device { vendor "NFINIDAT" product "InfiniBox.*" prio alua hardware_handler "1 alua" failback immediate detect_prio yes path_grouping_policy group_by_prio path_checker tur path_selector "round-robin 0" features "0" rr_weight priorities no_path_retry queue rr_min_io 1 # for kernels up to 2.6.31 rr_min_io_rq 1 # for kernels 2.6.31 or newer flush_on_last_del yes fast_io_fail_tmo 15 dev_loss_tmo "infinity" user_friendly_names no } } blacklist { }
Apply the new configuration and restart the multipathing daemon:
mpathconf --enable --with_multipathd y --with_chkconfig y /etc/init.d/multipathd restart chkconfig multipathd on
Create a new fibre channel driver parameters configuration file:
vi /etc/modprobe.d/infinidat.conf
The content of the file should be:
options qla2xxx ql2xmaxqdepth=128 ql2xenablemsix=0 ql2xextended_error_logging=507510784 options lpfc lpfc_hba_queue_depth=128 lpfc_lun_queue_depth=128 lpfc_devloss_tmo=5 lpfc_log_verbose=0xff
Create a new initial ramdisk image:
dracut -f /boot/initramfs-`uname -r`.img
Reboot the server:
reboot
Provisioning
Provisioning storage resources is done from InfiniBox (using either of the following : GUI, InfiniShell, API, InfiniSDK). Provisioning tasks are documented here:
- Accessing InfiniBox
- Creating a cluster and host on InfiniBox
- Provisioning volumes
- Creating a pool
- Relevant only if a pool was not created by the storage admin
- Creating a volume
- Creating a pool
- LUN masking
Disconnecting a host from InfiniBox
- Unmount the InfiniBox filesystems
- Unmapping a volume from a host or a cluster
- Deleting a volume (optional)
- This operation deletes all of the data from the volume
- This operation deletes the volume's snapshots
- This operation is irreversible
- Deleting a host
