Goal

The goal of this document is to provide a guidance on how to verify LUN properties on Sun Storage 7000 Unified Storage System. It will provide the steps needed to check the initiator group and target group, and to make sure your LUN is presented correctly to your initiator host.

To discuss this information further with Oracle experts and industry peers, we encourage you to review, join or start a discussion in the My Oracle Support Community - 7000 Series ZFS Appliances

Fix

1. Log on to the appliance CLI:

solaris$ ssh -l root 192.168.150.21

Password:

oratkyar1:>

2. Check LUN name by running following commands. The following example assumes that your LUN is in "default" project.

oratkyar1:> shares select default

oratkyar1:shares default> show

Properties:

aclinherit = restricted

atime = true

checksum = fletcher4

compression = off

dedup = false

compressratio = 100

copies = 1

creation = Wed Oct 12 2011 11:08:58 GMT+0000 (UTC)

logbias = latency

mountpoint = /export

readonly = false

recordsize = 128K

reservation = 0

secondarycache = all

nbmand = false

sharesmb = off

sharenfs = on

sharedav = off

shareftp = off

pool = pool-0

canonical_name = pool-0/local/default

default_group = other

default_permissions = 700

default_sparse = false

default_user = nobody

default_volblocksize = 8K

default_volsize = 0

exported = true

nodestroy = false

space_data = 3.50G

space_unused_res = 0

space_unused_res_shares = 0

space_snapshots = 2K

space_available = 6.28G

space_total = 3.50G

origin =

groups => View per-group usage and manage group quotas

replication => Manage remote replication

snapshots => Manage snapshots

users => View per-user usage and manage user quotas

3. Select LUN to extract the properties on the LUN.

oratkyar1:shares default> select iscsi_lun

oratkyar1:shares default/iscsi_lun> show

Properties:

checksum = fletcher4 (inherited)

compression = off (inherited)

dedup = false (inherited)

compressratio = 100

copies = 1 (inherited)

creation = Tue Dec 20 2011 12:45:44 GMT+0000 (UTC)

logbias = latency (inherited)

secondarycache = all (inherited)

lunguid = 600144F08ADE767F00004EF083780001

volsize = 1G

sparse = false

writecache = false

pool = pool-0

canonical_name = pool-0/local/default/iscsi_lun

exported = true (inherited)

nodestroy = false

space_data = 1.00G

space_snapshots = 0

space_total = 1.00G

space_available = 7.28G

initiatorgroup = iscsi_ig1

targetgroup = iscsitgrp1

lunumber = auto

assignednumber = 0

status = online

fixednumber = false

origin =



Children:

snapshots => Manage snapshots

replication => Manage remote replication

targetgroup indicates the target group this LUN belongs to. The IQN you should be specifying referring to this LUN is in iscsitgrp1 target group on this appliance.

initiatorgroup indicates the initiator group this LUN belongs to. Only the hosts with IQNs that belongs to iscsi_ig1 can see this LUN
