Dear Hicks/All,

1. When I executed the below command.

Code:

#mount

The disk c1t3d0 is not in use , pl find the below outputs

Code:

 # cat /etc/mnttab
/dev/dsk/c1t0d0s0       /       ufs     rw,intr,largefiles,logging,xattr,onerror=panic,dev=800000       1395166360
/devices        /devices        devfs   dev=5680000     1395166347
ctfs    /system/contract        ctfs    dev=56c0001     1395166347
proc    /proc   proc    dev=5700000     1395166347
mnttab  /etc/mnttab     mntfs   dev=5740001     1395166347
swap    /etc/svc/volatile       tmpfs   xattr,dev=5780001       1395166347
objfs   /system/object  objfs   dev=57c0001     1395166347
sharefs /etc/dfs/sharetab       sharefs dev=5800001     1395166347
/platform/SUNW,SPARC-Enterprise-T5220/lib/libc_psr/libc_psr_hwcap2.so.1 /platform/sun4v/lib/libc_psr.so.1       lofs    dev=800000      1395166354
/platform/SUNW,SPARC-Enterprise-T5220/lib/sparcv9/libc_psr/libc_psr_hwcap2.so.1 /platform/sun4v/lib/sparcv9/libc_psr.so.1       lofs    dev=800000      1395166354
fd      /dev/fd fd      rw,dev=5980001  1395166360
swap    /tmp    tmpfs   xattr,dev=5780002       1395166361
swap    /var/run        tmpfs   xattr,dev=5780003       1395166361
/dev/dsk/c1t0d0s3       /opt    ufs     rw,intr,largefiles,logging,xattr,onerror=panic,dev=800003       1395166366
-hosts  /net    autofs  nosuid,indirect,ignore,nobrowse,dev=5a40001     1395166380
auto_home       /home   autofs  indirect,ignore,nobrowse,dev=5a40002    1395166380

So Kindly let me know whether this particular disk c1t3d0 is in use or not.

Because if it is in use , we can take the backup of this and do the patching.

2. And also , on one another Server , I see the SVM is also configured..

/dev/md/dsk/d10 /infovista ufs rw,intr,largefiles,logging,xattr,onerror=panic,dev=154000a

So in this case ,what we should do after splitting the hardware mirror ,

Thanks and Regards ,
Rj

mkdevmaps

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
