Ken, For any dasd greater than dasdz you must run mknod mknod -m 660 /dev/dasdaa b 94 104 mknod -m 660 /dev/dasdaa1 b 94 105 mknod -m 660 /dev/dasdab b 94 108 mknod -m 660 /dev/dasdab1 b 94 109
Get the major/minor node numbers from a cat of /proc/dasd/devices I don't create nodes for partitions 2 and 3 because I don't use them. No harm in doing it though mknod -m 660 /dev/dasdaa2 b 94 106 etc Betsie ----- Original Message ----- From: "Ken Vance" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, April 22, 2004 9:22 AM Subject: more than 26 disks > Hi, > > We were adding a large number of disks to our SuSE8 image.
