Solaris: how to compare pkgs , version and releases

Posted in Solaris at 12:40 pm by alessiodini

Yesterday a customer asked me to compare every package/version/revision between a test system and production system.
The goal was to achieve these informations on .csv file. For this purpose a wrote a script and i was funny to use perl ( after some month ). I based my script on pkginfo -l command output.

Here there is the link of the script!

Solaris: how to resolve logical controller to physical path

Posted in Solaris at 3:48 pm by alessiodini

Yesterday i was envolved in troubleshooting a SAN problem on a Solaris 10 system. During that task i need to resolve physical path from logical controller.
Logical Controller:

c3 fc-fabric connected configured unknown
c3::5006048c49aeb359 disk connected configured unknown
c3::5006048c49d51707 disk connected configured unknown

c6 fc-fabric connected configured unknown
c6::5006048449d51728 disk connected configured unknown
c6::5006048c49aeb356 disk connected configured unknown

Physical Paths:

luxadm -e port
/devices/pci@5c,600000/SUNW,qlc@1/fp@0,0:devctl CONNECTED
/devices/pci@5c,600000/SUNW,qlc@1,1/fp@0,0:devctl NOT CONNECTED
/devices/pci@7c,600000/SUNW,qlc@1/fp@0,0:devctl CONNECTED
/devices/pci@7c,600000/SUNW,qlc@1,1/fp@0,0:devctl NOT CONNECTED

My question was: “I have to verify c3 … which of physical path does correspond to it?”
I was funny to answer to my question

Starting from c3:

c3::5006048c49aeb359
c3::5006048c49d51707

Starting from the first physical path available:

/devices/pci@5c,600000/SUNW,qlc@1/fp@0,0:devctl

luxadm -e dump_map /devices/pci@5c,600000/SUNW,qlc@1/fp@0,0:devctl
Pos Port_ID Hard_Addr Port WWN Node WWN Type
0 15300 0 5006048c49d51707 5006048c49d51707 0×0 (Disk device)
1 17900 0 5006048c49aeb359 5006048c49aeb359 0×0 (Disk device)
2 12b00 0 210000e08b936d1f 200000e08b936d1f 0x1f (Unknown Type,Host Bus Adapter)

Wow found at first time! I was a little bit lucky

So , it’s possible to combine output from cfgadm/luxadm commands for retrieve physical path!

Solaris 10: zcons online message resolution

Posted in Solaris at 11:32 am by alessiodini

Today i worked about an alarm. I read this message:

genunix: [ID 408114 kern.info] /pseudo/zconsnex@1/zcons@6 (zcons6) online

So , it seems a zone had a offline/online. I did not have more info , so i was a little bit curious about to resolve zcons@6 to local zone name.
Accomplishing this , i found 2 methods:

1)

# pwd
/dev/zcons

# ls -lR
(…)
./system95:
total 4
lrwxrwxrwx 1 root root 56 Mar 27 11:26 masterconsole -> ../../../devices/pseudo/zconsnex@1/zcons@6:masterconsole
lrwxrwxrwx 1 root root 54 Mar 27 11:26 zoneconsole -> ../../../devices/pseudo/zconsnex@1/zcons@6:zoneconsole

2)

# prtconf -v /devices/pseudo/zconsnex@1/zcons@6
(…)
value=’system95′
(…)

Solaris 10: modify multiple zfs datasets and add a filesystem to multiple zones in few line

Posted in Solaris at 11:13 am by alessiodini

Yesterday i was very funny doing a task. I had to upgrade /export/home dataset to “legacy” and add that filesystem within xml for 26 local zones.

For this purpose , i wrote first a script that checks every ‘/export/home dataset’ without legacy attribute.
the script is here

I tried it on a global zone:

root@system8 # ./check_legacy
rootdg_system241/export_home 24K 8.21G 24K /mnt_system241/root/export/home
rootdg_system242/export_home 2.55M 7.81G 2.55M /mnt_system242/root/export/home
rootdg_system243/export_home 285M 7.52G 285M /mnt_system243/root/export/home
rootdg_system244/export_home 459M 7.37G 459M /mnt_system244/root/export/home
rootdg_system245/export_home 347M 7.94G 347M /mnt_system245/root/export/home
rootdg_system246/export_home 17.4M 6.27G 17.4M /mnt_system246/root/export/home
rootdg_system247/export_home 12.0M 8.09G 12.0M /mnt_system247/root/export/home
rootdg_system261/export_home 285M 7.25G 285M /mnt_system261/root/export/home

After i did something similar to next command( zfs.log has previous output ):

root@system8 # for i in `cat /tmp/zfs.log | awk ‘{ print $1 }’`; do echo zfs set mountpoint=legacy $i; done

zfs set mountpoint=legacy rootdg_system241/export_home
zfs set mountpoint=legacy rootdg_system242/export_home
(…)

This task required an /export/home umount, so i mounted them manually after.
As last step i wrote a 1line command for configure /export/home within xml for every zone. The code is here

Solaris 10 and ufs filesystem greather than 1tb

Posted in Solaris at 4:08 pm by alessiodini

Today i got a task about a resize. I have to grow a ufs filesystem more than 1 tb.
In my experience i learned that a ufs filesystem needs to be created with multi-terabyte support at beninning or this task will require a new filesystem creation !

I did not know how verify the multi-tera support , i looked on the web but i found an answer from colleague.
so let’s see
( ufs filesystem without support, i tried on my virtual machine )

vxlab:>fstyp -v /dev/rdsk/c2t0d0s2 | head -2
ufs
magic 11954 format dynamic time Wed Feb 22 15:41:04 2012

( ufs filesystem with support , i tried on my virtual machine )

vxlab:>fstyp -v /dev/rdsk/c2t0d0s2 | head -2
ufs
magic decade format dynamic time Wed Feb 22 17:05:38 2012

So , when decade exists we have a multi-tera support!
