Obtaining kernel patch release date without sunsolve is possible!
On running system i can run these commands:

grep Date /var/sadm/patch/`uname -v | cut -f2 -d’_’ `/README.*|awk ‘{print $2}’

Example:

# grep Date /var/sadm/patch/`uname -v | cut -f2 -d’_’ `/README.*|awk ‘{print $2}’

Today i upgrade this system

I encountered this error during a live upgrade activity.
After running lucreate command i had this error:

Template entry -:/dev/dsk/c0t2d0s1:swap skipped.

luconfig: ERROR: Template filesystem definition failed for -, all devices are not applicable..
ERROR: Configuration of boot environment failed.

During my analsyis i found that c0t2d0s1 doesn’t have tag “swap” but “unassigned”.
I changed in swap , obtaining from format:

[...]
1 swap wu 5141 – 6683 3.00GB (1543/0/0) 6295440
[...]

I tried to run lucreate and all was fine!!!

On this system i must create a flash archive for backup.
Creating a flar is simple , in this case i use flarcreate command as follow:

flarcreate -n soapbo01fs_archive -c -x /mnt1 -S /mnt1/flar_soapbo01fs

where:
-n soapbo01fs_archive = the name of Flash archive
-c = the archive is compressed
-x /mnt1 = excludes /mnt1 ( in this case i use this directory as location of archive )
-S = do not include size information ( without this the creation of archive is quickly )
/mnt1/flar_soapbo01fs = the location where the archive is created

So:

# flarcreate -n soapbo01fs_archive -c -x /mnt1 -S /mnt1/flar_soapbo01fs
Full Flash

Today on a Solaris 10 system ( global zone ) i discovered this error:

#zoneadm list -cv
ID NAME STATUS PATH BRAND IP
0 global running / native shared
[...]
zoneadm: local13: could not get brand name: Wrong document type
[...]

What’s happend here!?!
It can be a problem related to the syntax of /etc/zones/local13.xml file or /etc/zones/index
In this case /etc/zones/local13.xml was missing… i don’t know why

When i run du -sh command i can see every file size , but if i want obtain a ordered list?
With these commands i can accomplish this:

[root@server]#pwd
/var

[root@server]# \du -sh * | tee /tmp/prova.txt | grep G | sort -rn ; cat /tmp/prova.txt | grep M | sort -rn ; cat /tmp/prova.txt | grep K | sort -rn ; rm /tmp/prova.txt

GOOD!!!

I’m updating java on a solaris system and when i run the .sh script i obtain the following error:

The download file appears to be corrupted. Please refer
to the Troubleshooting section of the Installation
Instructions on the download page for more information.
Please do not attempt to install this archive file.

This error is caused because i upload the file in ascii mode , not binary!!

Today a developer asks to me and Emanuel where is possible obtain the allocation of inodes on mounted filesystem under Solaris 10.

We found that for this purpose the df command can be used , as follow:

root@sb13 # df -F ufs -o i /
Filesystem iused ifree %iused Mounted on
/dev/dsk/c16t6d0s0
199587 1664093 11% /

I’m connected to a system and i want see if this system is a global or local zone.
What can i do?

For this purpose i can use the zonename command as follow:

root@ssb30 # zonename
global
root@ssb30 #

in this case ssb30 is a global zone

root@ssc10 # zonename
ssc10
root@ssc10 #

in this case ssc10 is a local zone
very simple!

I obtained this errore because i tried to mount a ufs filesystem when the volume was vxfs!

root@gri2 # mount /dev/vx/dsk/zonepath_gri2_DG/zonepath_gri2_vol01 /zone/gri2
May 25 16:23:10 gri2 ufs: NOTICE: mount: not a UFS magic number (0×0)
mount: /dev/vx/dsk/zonepath_gri2_DG/zonepath_gri2_vol01 is not this fstype

I didn’t know that the volume was vxfs , i verified with:

root@gri2 # fstyp /dev/vx/dsk/zonepath_gri2_DG/zonepath_gri2_vol01
vxfs

So , i mounted the filesystem with vxfs option:

mount -F vxfs /dev/vx/dsk/zonepath_gri2_DG/zonepath_gri2_vol01 /zone/gri2
root@gri2 #
