No local disk in format in Solaris
I have Solaris-10 server. During troubleshooting of some storage issue, I removed disk entries from /dev/dsk and /dev/rdsk
HTML Code:
rm /dev/vx/dmp/*
rm /dev/vx/rdmp/*
rm /dev/dsk/*
rm /dev/rdsk/
And rebooted the box. That recreated device tree for SAN disks, but I do not see c1t0d0s0 and c1t1d0s0 disk in format output.
HTML Code:
root@oradbprod_apps01:/# ls -l /dev/dsk | grep -i c1t1d0
lrwxrwxrwx 1 root root 51 Mar 5 22:02 c1t1d0s0 -> ../../devices/ssm@0,0/pci@18,700000/scsi@2/sd@1,0:a
lrwxrwxrwx 1 root root 51 Mar 6 09:50 c1t1d0s7 -> ../../devices/ssm@0,0/pci@18,700000/scsi@2/sd@1,0:h
root@oradbprod_apps01:/# ls -l /dev/dsk | grep -i c1t0d0
lrwxrwxrwx 1 root root 51 Mar 5 22:02 c1t0d0s0 -> ../../devices/ssm@0,0/pci@18,700000/scsi@2/sd@0,0:a
lrwxrwxrwx 1 root root 51 Mar 6 09:50 c1t0d0s7 -> ../../devices/ssm@0,0/pci@18,700000/scsi@2/sd@0,0:h
root@oradbprod_apps01:/# ls -l /dev/rdsk | grep -i c1t1d0
lrwxrwxrwx 1 root root 55 Mar 6 09:50 c1t1d0s7 -> ../../devices/ssm@0,0/pci@18,700000/scsi@2/sd@1,0:h,raw
root@oradbprod_apps01:/# ls -l /dev/rdsk | grep -i c1t0d0
lrwxrwxrwx 1 root root 55 Mar 6 09:50 c1t0d0s7 -> ../../devices/ssm@0,0/pci@18,700000/scsi@2/sd@0,0:h,raw
root@oradbprod_apps01:/# echo | format | grep -i c1t1d0
root@oradbprod_apps01:/# echo | format | grep -i c1t0d0
root@oradbprod_apps01:/#
Due to this reason, I can not label and mirror disks. Can somebody help me in bringing them back in format output ?

mkdevalloc
mkdevalloc(1M) System Administration Commands mkdevalloc(1M)
NAME
mkdevalloc - Make device_allocate entries
SYNOPSIS
/usr/sbin/mkdevalloc
DESCRIPTION
The mkdevalloc command writes to standard out a set of device_allocate(4) entries describing the system's frame buffer, audio and removable
media devices.
The mkdevalloc command is used by the init.d(4) scripts to create or update the /etc/security/device_allocate file.
Entries are generated based on the device special files found in /dev. For the different categories of devices, the mkdevalloc command
checks for the following files under /dev:
audio /dev/audio, /dev/audioctl, /dev/sound/...
tape /dev/rst*, /dev/nrst*, /dev/rmt/...
floppy /dev/diskette, /dev/fd*, /dev/rdiskette, /dev/rfd*
removable disk /dev/sr*, /dev/nsr*, /dev/dsk/c0t?d0s?, /dev/rdsk/c0t?d0s?
frame buffer /dev/fb
All entries set the device-minimum and device-maximum fields to the hex representations of ADMIN_LOW and ADMIN_HIGH, respectively. The
device-authorization field is set to solaris.device.allocate, except for the framebuffer entry, where it is set to *. The device-name,
device-type and device-clean fields are set to the following values:
device-name device-type device-clean
audio audio audio audio_clean_wrapper
tape mag_tape_0,1,... st st_clean
floppy floppy_0,1,... fd disk_clean
removable disk cdrom_0,1,... sr disk_clean
frame buffer framebuffer fb /bin/true
