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 ?

mkdevmaps(1M)                                             System Administration Commands                                             mkdevmaps(1M)

NAME

       mkdevmaps - make device_maps entries

SYNOPSIS

       /usr/sbin/mkdevmaps

DESCRIPTION

       The  mkdevmaps  command  writes  to standard out a set of device_maps(4) entries describing the system's frame buffer, audio, and removable
       media devices.

       The mkdevmaps command is used by the init.d(4) scripts to create or update the /etc/security/device_maps file.

       Entries are generated based on the device special files found in /dev. For the different  categories  of  devices,  the  mkdevmaps  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/dsk/c0t?d0s?, /dev/rdsk/c0t?d0s?
       frame buffer    /dev/fb
