When preparing the host to work with (infinihost settings check) InfiniBox, some additional software packages are required to be installed and some configuration must be applied.

The host readiness tool, infinihost, checks for the existence and correctness of the following items.

Software packages

General checks:

FC connectivity

• no mixed ports on multiple storage arrays - 3670213 Host initiator ports exclusivity test
• dual initiator to the InfiniBox - 3670216 Host should be connected through more than one initiator port
• multiple nodes connectivity - 3670219 Host should be connected to more than one Node of each InfiniBox
• not passing maximum paths - 13929579 Host has too many connected paths to InfiniBox
• large amount of volumes per host - 14942510 Host sees too many block devices

FC HBA

• verify that the HBA is supported within our support matrix (see: INFINIDAT software compatibility).

Devices

• volumes that don't have a multipath device - 1704801 Multipath device doesn't exist for volume
• all reported INFINIDAT LUNs have a block device - 22157347 Missing block devices
• path count for all INFINIDAT MPIO devices doesn't exceed - 22157362 Missing paths for MPIO devices

Linux checks:

• configure multipath blacklist of local devices - 7667992 Local blacklist in multipath configuration

FC HBA

• modify the driver parameters to take effect on a normal driver load and in initrd - 3670125 The HBA driver is not configured according to the best practices

iSCSI

• iSCSI initiator software is installed - 22155590 Installing the iSCSI Initiator on Linux
• node.startup = automatic in file /etc/iscsi/iscsid.conf - Linux iSCSI configuration should be set to automatic login
• node.leading_login = No in file /etc/iscsi/iscsid.conf - Linux iSCSI should not use leading login
• node.session.queue_depth = 128 in file /etc/iscsi/iscsid.conf - Linux iSCSI configuration should set queue depth to 128
  
• node.session.timeo.replacement_timeout = 120 in file /etc/iscsi/iscsid.conf - Linux iSCSI configuration should set replacement timeout to 120
  
• iscsid is running - Linux: The iSCSI service must be running
• iscsid automatically loads on boot - Linux: The iSCSI service must be loaded at boot time
• iSCSI name of the host is a valid IQN - 37430551 iSCSI name must be a valid IQN

Windows checks:
