I had used 4 sub-channels instead of 80 for every linux, like what Steffen and Ralph recommanded.
And HW guy also modified configuration on storage side, here is what he did: (6 linux share 20 disks) (1)Allocating 20 volumes. (2)Define volume group 1 that contains 24 volumes. (3)Define host connections from host_1 to host_6, every host connection contains 4 sub-channels WWPN on MF side. (4)Assign all host connections to volume group 1. On one linux, I add disk1 to disk8 normally, every disk use 4 paths (subchannel:3300, 3f00, 4300, 4E00) When I add disk9, 3300,4300,4E00 is OK, but an error occured when input 3f00. This time, error shows different status. Last time, input sub-channel, can not get WWPN of hba_port This time, input sub-channel, can get WWPN of hba_port, but can not get WWPN list of LUN. On linux, a dialog poped up, showing: zfcp_san_disc:Unable to activate LUN 0 The most strange thing is that I had use 3f00 to define disk1 to disk8, but error suddenly occured. Raymond, I had get /console/data/iqyylog.log for previous error and this time error( happend at 15:11). Do you know who can help us to analyze this file because I can not recognize the characters in this log. I can send this log by email. ---------------------------------------------------------------------- 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/
