fcp initiator group (not logged in)

Hello,

Recently I have added an fcp initiator (wwpn) to an exisiting igroup. after adding , I do not see it as "logged in".. The zoning is good.. Do we need to change some setting or add both the initiators in the igroup together as a best practice.?

        Member: c0:50:76:03:e8:aa:00:52 (not logged in)

        UUID: 50aed88c-c6a6-11e1-ae2b-00a09820168b

        ALUA: Yes

zone config:

* fcid 0x0c0200 [pwwn 50:0a:09:87:8f:6f:95:82]

* fcid 0x0c0300 [pwwn 50:0a:09:86:8f:6f:95:82]

* fcid 0x0b0027 [pwwn c0:50:76:03:e8:aa:00:52]

any ideas anyone?

Hi,

Is the pwwn correct? Did you rescan disks / hba on the host after adding initiator to igroup?

Hi Radek,

Thanks for the response.  Yes the pwwn correct on the switches.. Is rescanning required on the host side ?

The host is already seeing the LUN over a single path. I added a redundant path today with the other initiator of the host on the other fabric.

        Member: c0:50:76:03:e8:aa:00:52 (not logged in)------- redundant initiator of the host which I added

        UUID: 50aed88c-c6a6-11e1-ae2b-00a09820168b

        ALUA: Yes

zone config:

* fcid 0x0c0200 [pwwn 50:0a:09:87:8f:6f:95:82]

* fcid 0x0c0300 [pwwn 50:0a:09:86:8f:6f:95:82]

* fcid 0x0b0027 [pwwn c0:50:76:03:e8:aa:00:52]------ redundant initiator of the host..

The zoning and pwwn looks fine. Is there something I have missed after adding the initiator to the igroup?

The sequence I added it are:

1. Zoning on the switch.

2.Add the initiator to the existing igroup

I'd say the missing step is rescanning on the host.

Re: fcp initiator group (not logged in)

Thanks Radek, I will try and let you know.

Re: fcp initiator group (not logged in)

Hello Radek,

Rescanning on the host worked. Both the initiators in the igroup is showing as logged in .. Many thanks for your help.

Cheers

Rahul
