Prepare the FlashArray with the Host, Volume, and Host IQN

1. On the Linux host, collect the IQN:

# cat /etc/iscsi/initiatorname.iscsi

2. On FlashArray, create a host:

purehost create <Linux hostname>

where

<Linux hostname> is the desired hostname.

3. Configure FlashArray host with IQN:

purehost setattr --addiqnlist <IQN number> <Linux hostname>

where

<IQN number> is the initiator IQN number gathered in step 1.

<Linux hostname> is the hostname created in step 2.

4. On the FlashArray, create a volume:

purevol create <volume name> --size <size>

where

<volume name> is the desired volume name.

<size> is the desired volume size (GB or TB suffix).

5. Connect the host to volume:

purevol connect <volume name> --host <host name>

where

<volume name> is the name of the volume.

<host name> is the name of the host. 

6. On the FlashArray, collect iSCSI interface IPs:

pureport list

7. On Linux Host, discover the target iSCSI portals:

# iscsiadm -m discovery -t st -p <FlashArray iSCSI IP>:3260

where

<FlashArray iSCSI IP> is the iSCSI interface IP address from either collected in step 6.

8. From your Linux Host, log in to the FlashArray iSCSI target portals on both controllers:

# iscsiadm -m node -p <FlashArray iSCSI IP CT0> --login
# iscsiadm -m node -p <FlashArray iSCSI IP CT1> --login

where

<FlashArray iSCSI IP CT0>  is the iSCSI interface IP address of controller 0 collected from step 6
<FlashArray iSCSI IP CT1>  is the iSCSI interface IP address of controller 1 collected from step 6

9. Add automatic iSCSI login on boot:

# iscsiadm -m node -L automatic

10. Confirm the FlashArray volume has multiple paths with multipath -ll. A multipathed volume should be represented by a device-mapped ID, as shown in in the example below [3624a93702b60622e2b014a2200011011] and [3624a93702b60622e2b014a2200011010]:
