Hello all, This is kind of a strange one but we've about run out of things to look at. The two servers having boot problems are:
Psuedo Name: SUSE Linux Enterprise Server 10 (s390x) Rev: 4 Kernel 2.6.16.60-0.103.1-default Machine: s390x and we have the disks being SRDF'd to a remote datacenter. We have hundreds of servers that we are SRDF'g too and they have not seen this issue. SRDF is suspended and the remote disks are R/W to the host. When the server starts up in the remote side, we see the usual preamble of: 15:36:14 Starting udevd Creating devices 15:36:14 Loading scsi_mod SCSI subsystem initialized Loading sd_mod Loading dasd_mod 15:36:14 Loading dasd_diag_mod Loading dasd_fba_mod Loading dasd_eckd_mod Loading scsi_transport_fc Loading qdio 15:36:14 qdio: loading QDIO base support version 2 Loading zfcp Activating DASDs: 0.0.01b0:0dasd(eckd): 0.0.01b0: PSF-SSC on storage subsystem EMC.080000000AGRDK.ca01 returned rc=0 dasd(eckd): 0.0.01b0: 3390/0C(CU:3990/01) Cyl:150 Head:15 Sec:224 dasd(eckd): 0.0.01b0: (4kB blks): 108000kB at 48kB/trk compatible disk layout dasda:VOL1/ 0X01B0: dasda1 0.0.01b1:0dasd(eckd): 0.0.01b1: PSF-SSC on storage subsystem EMC.080000000AGRDK.c001 returned rc=0 dasd(eckd): 0.0.01b1: 3390/0C(CU:3990/01) Cyl:730 Head:15 Sec:224 dasd(eckd): 0.0.01b1: (4kB blks): 525600kB at 48kB/trk compatible disk layout dasdb:VOL1/ 0XDA11: dasdb1 .... more ... .... goes into zfcp configuration ... .... then ...

Some things we've tried: - Mount the disk on another server; looks fine, files/directories all there; fsck clean - Created a new disk, dasdfmt/fdasd/mkfs ext3, then copied all the files from the orig disk to the new disk - still FAILED - Used PIPEDDR to copy the original system's 1b1 disk to the remote system - still FAILED - Tried booting from a working server's 1b0 - still FAILED - Tried booting using the working server's 1b1 - WORKED Something is up with that 1b1 but I can't even begin to know what to look for. It seems like it has to be some file on the disk b/c creating a brand new disk didn't help any. Anyone have any ideas?
