Thank you very much. The SCSIDISC tool helped. The system is now running. The tool actually showed 6 different WWPNs per FCP device (2000 and 3000) but the output was only 'complete' for 1 of these with UUID/vendor/PROD etc filled out in the SCSIDISC OUT file. I used the info for the 1 complete WWPN and the system IPLed.
Our linux guy also says that only the 3000 device appeared in zipl.conf - he says the installer built the file. Can he manually add the equivalent 2000 device info? Anyway thanks again. We obviously have some internal stuff to sort out. -----Original Message----- From: Linux on 390 Port [mailto:[email protected]] On Behalf Of Steffen Maier Sent: Monday, February 29, 2016 8:48 AM To: [email protected] Subject: Re: IPL from SAN On 02/29/2016 02:21 PM, Rothman, Peter wrote: > This is per our Linux sysadmin. > I have asked him about the WWPN - FYI this was the posted.

From the host / Linux perspective, the LUNs are behind the target port WWPN. In a running Linux, you can use "lszfcp -P" to see all target ports that zfcp could discover [http://www-01.ibm.com/support/knowledgecenter/linuxonibm/com.ibm.linux.z.lgdd/lgdd_t_fcp_wrk_pinfo.html http://www-01.ibm.com/support/knowledgecenter/linuxonibm/com.ibm.linux.z.ldsg/ldsg_r_scsiipl_sanaddr.html] If you don't have Linux running, you could use the z/VM tool SCSIDISC to discover target ports [http://www-01.ibm.com/support/knowledgecenter/SSB27U_6.3.0/com.ibm.zvm.v630.hcpb7/scsidisc.htm], or you can use "FCP SAN Explorer" on the HMC/SE [presentation I referenced in an earlier mail]. Depending on your zoning and LUN masking you need to chose the correct target port if multiple ports were discovered. Earlier you wrote that you could successfully install and reboot. Alternatively, you can use such a running Linux instance and run "lsreipl" to figure out the necessary FCP addressing parameters for a manual IPL. The Linux distribution installer figured this out already.

The zone also contains the storage target port(s) which the host / initiator needs for accessing the LUNs. -- Mit freundlichen Grüßen / Kind regards Steffen Maier Linux on z Systems Development IBM Deutschland Research & Development GmbH Vorsitzende des Aufsichtsrats: Martina Koederitz Geschaeftsfuehrung: Dirk Wittkopp Sitz der Gesellschaft: Boeblingen Registergericht: Amtsgericht Stuttgart, HRB 243294 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/ _______________________________________________________________________ *** This is an EXTERNAL email.
