Server side manchi_babu cheppindi follow ayipo....storage side troubleshooting steps ivi....


[b]FROM STORAGE SIDE: [/b]

Verify iscsi/fcp license is added in storage
Verify iscsi/fcp session is logged in from server side
Verify luns are mapped to the corresponding igroup.
Verify whether correct host type is mentioned while creating igroup and lun
Verify whether correct iqn/wwpn number is added to [color=#ff0000]igroup[/color]
Verify zoning is properly configured from switch side.

asalu license unda? correct wwpns ke map chesama? zoning correct ga unda? server type (linux/sloaris/windows anedi mention chesthamu lun create chese time lo) correct ga unda? ivvani check chesuko....anni correct ga unte storage side nunchi no issue....

ya igroup anedi netapp concept....SAN lo luns create chestham....luns ni server ki map chestham....igroup anedi server wwpn details...oka lun ni min. 2 hba's ki map cheyali for redundancy....

[b]Lun create chesthunna:[/b]


lun create -s size -t OS type path
Example: lun create -s 50m -t solaris /vol/vol2/qtree1/lun1 (gonna create lun1 in qtree1)


how 2 use this lun?
need 2 create a igroup
igroup create -t OStype -f name wwpn
igroup create -t solaris -f server1 10:04:..............


lun map path servername lunname
lun map /vol/vol2/qtree/lun1 server1 lun1

Summarizing

ISCSI is less expensive when compared to FC

ISCSI is easy to implement, because it uses Ethernet cables.

When we use FC we have to create zones a logical relation between host and LUN. where as in ISCSI no zones were created.

ISCSI is more secure than FC.


Bhayya ikkada oka doubt. ISCSI ki chala advantages unnappudu real time lo ekkuva FC enduku vadutunnaru.
