Subject: Re: kern/26044: disklabel fails to write to SCSI disk on Netra T1 (sparc64)
Date: Sun, 21 Aug 2005 22:28:58 +0100

 	Hello,
 
 I've got exactly the same problem on this system ...
 
 NetBSD sheridan.zhadum.de 3.99.7 NetBSD 3.99.7 (SHERIDAN) #0: Sun Jul 10 18:15:22 BST 2005  tron@lyssa.zhadum.de:/export/scratch/tron/build.18302a/sys/compile/SHERIDAN sparc64
 
 ... with this disk:
 
 sd2 at scsibus1 target 0 lun 0: <IBM, DCAS-34330, S65A> disk fixed
 sd2: 4134 MB, 8205 cyl, 6 head, 171 sec, 512 bytes/sect x 8467200 sectors
 sd2: sync (50.00ns offset 15), 8-bit (20.000MB/s) transfers, tagged queueing
 
 Any attempts to label the disk fail:
 
 tron@sheridan:/home/tron#disklabel -R -r sd2 /var/tmp/tt
 sd2: no disk label
 
 Attempts to create filesystem on it fail, too:
 
 tron@sheridan:/home/tron#newfs /dev/rsd2a
 /dev/rsd2a: 128.2MB (262656 sectors) block size 8192, fragment size 1024
         using 4 cylinder groups of 32.06MB, 4104 blks, 7936 inodes.
 wtfs: write error for sector 262655: Undefined error: 0
 
 The disklabel file is fine. It's copy of the disklabel from a NetBSD-sparc
 machine which uses a disk of the same time:
 
 sd0 at scsibus0 target 0 lun 0: <IBM, DCAS-34330, S65A> disk fixed
 sd0: 4134 MB, 8205 cyl, 6 head, 171 sec, 512 bytes/sect x 8467200 sectors
 sd0: sync (100.00ns offset 15), 8-bit (10.000MB/s) transfers, tagged queueing
 root on sd0a dumps on sd0b
 
 It is also *not* problem with the disk because I can label and newfs it
 with Solaris 9 without problems.
 
 	Kind regards
