drive 0" 41.Sh DESCRIPTION 42NOTE: This driver has not been ported from 43.Bx 4.4 44yet. 45.Pp 46This is a generic 47.Tn UNIBUS 48storage module disk driver. 49It is specifically designed to work with the 50Emulex 51.Tn SC-21 52and 53.Tn SC-31 54controllers. 55It can be easily 56adapted to other controllers (although bootstrapping will 57not necessarily be directly possible.) 58.Pp 59The script 60.Xr MAKEDEV 8 61should be used to create the 62.Nm up 63special files; consult 64.Xr mknod 8 65if a special file needs to be made manually. 66It is recommended as a security precaution to not create special files 67for devices which may never be installed. 68.Sh DISK SUPPORT 69The driver interrogates the controller's holding register 70to determine the type of drive attached. 71The driver recognizes seven different drives: 72.Tn CDC 739762, 74.Tn CDC 759766, 76.Tn AMPEX DM Ns 980 , 77.Tn AMPEX 789300, 79.Tn AMPEX 80Capricorn, 81.Tn FUJITSU 82160, and 83.Tn FUJITSU 84Eagle 85(the Eagle is not supported by the SC-21). 86.Pp 87Special file names begin with 88.Sq Li up 89and 90.Sq Li rup 91for the block and character files respectively. 92The second component of the name, a drive unit number in the range 93of zero to seven, is represented by a 94.Sq Li \&? 95in the disk layouts below. 96The last component of the name, the file system partition, is 97designated by a letter from 98.Sq Li a 99to 100.Sq Li h 101which also corresponds to a minor device number set: zero to seven, 102eight to 15, 16 to 23 and so forth for drive zero, drive two and drive 103three respectively (see 104.Xr physio 4 ) . 105The location and size (in 512 byte sectors) of the 106partitions for the above drives: 107.Bl -hang 108.It Tn CDC No 9762 partitions 109.Bl -column diskx undefined length

normally used for the root file system, 192the up?b partition as a paging area, 193and the up?c partition for pack-pack copying (it maps the entire disk). 194On 160M drives the up?g partition maps the rest of the pack. 195On other drives both up?g and up?h are used to map the 196remaining cylinders. 197.Sh FILES 198.Bl -tag -width Pa -compact 199.It Pa /dev/up[0-7][a-h] 200block files 201.It Pa

specified 208filesystem block number(s), 209which are logical block numbers on the indicated partition. 210The contents of the cs2, er1 and er2 registers are printed 211in octal and symbolically with bits decoded. 212The error was either unrecoverable, or a large number of retry attempts 213(including offset positioning and drive recalibration) could not 214recover the error. 215.It "up%d: write locked." 216The write protect switch was set on the drive 217when a write was attempted. 218The write operation is not recoverable. 219.It "up%d: not ready." 220The drive was spun down or off line when it was 221accessed. 222The I/O operation is not recoverable. 223.It "up%d: not ready (flakey)." 224The drive was not ready, but after 225printing the message about being not ready (which takes a fraction 226of a second) was ready. 227The operation is recovered if no further errors occur. 228.It "up%d%c: soft ecc reading fsbn %d[-%d]." 229A recoverable ECC error occurred on the 230specified sector of the specified disk partition. 231This happens normally 232a few times a week. 233If it happens more frequently than this the sectors where the errors 234are occurring should be checked to see if certain cylinders on the 235pack, spots on the carriage of the drive or heads are indicated. 236.It "sc%d: lost interrupt." 237A timer watching the controller detecting 238no interrupt for an extended period while an operation was outstanding. 239This indicates a hardware or software failure. 240There is currently a hardware/software problem with spinning down 241drives while they are being accessed which causes this error to 242occur. 243The error causes a 244.Tn UNIBUS 245reset, and retry of the pending operations. 246If the controller continues to lose interrupts, this error will recur 247a few seconds later. 248.El 249.Sh SEE ALSO 250.Xr vax/hk 4 , 251.Xr vax/hp 4 , 252.Xr vax/uda 4 253.Sh HISTORY 254The 255.Nm up 256driver appeared in 257.Bx 4.0 . 258.Sh BUGS 259A program to analyze the logged error information (even in its 260present reduced form) is needed. 261.Pp 262The partition tables for the file systems should be read off of each 263pack, as they are never quite what any single installation would prefer, 264and this would make packs more portable. 265
