Clusterware Clusterware

Get Solaris release information

# pkg info kernel | \
  nawk -F '.' '
/Build Release:/{
  solaris=$NF;
}
/Branch:/{
  subrel=$3;
  update=$4;
}
END{
  printf "Solaris %d.%d Update %d\n",solaris,subrel,update;
}'

Needed Solaris packages

Install pkg dependencies

# pkg install developer/assembler
# pkg install developer/build/make
# pkg install x11/diagnostic/x11-info-clients

Check pkg dependencies

# pkg list \
    developer/assembler \
    developer/build/make \
    x11/diagnostic/x11-info-clients

User / group settings

Groups

# groupadd -g 186 oinstall
# groupadd -g 187 asmadmin
# groupadd -g 188 asmdba
# groupadd -g 200 dba

User

# useradd \
    -u 102 \
    -g oinstall \
    -G asmdba,dba \
    -c "Oracle DB" \
    -m -d /export/home/oracle \
    oracle
# useradd \
    -u 406 \
    -g oinstall \
    -G asmdba,asmadmin,dba \
    -c "Oracle Grid" \
    -m -d /export/home/grid \
    grid

Generate ssh public keys

# su - grid
$ ssh-keygen -t rsa -b 2048
Generating public/private rsa key pair.
Enter file in which to save the key (/export/home/grid/.ssh/id_rsa): <Enter>
Created directory '/export/home/grid/.ssh'.
Enter passphrase (empty for no passphrase): <Enter>
Enter same passphrase again: <Enter>
Your identification has been saved in /export/home/grid/.ssh/id_rsa.
Your public key has been saved in /export/home/grid/.ssh/id_rsa.pub.
The key fingerprint is:
..:..:.. grid@grid01
$ cat .ssh/id_rsa.pub > .ssh/authorized_keys
$ chmod 600 .ssh/authorized_keys
$ vi .ssh/authorized_keys

Add the public key of other nodes.

After that do this on all other nodes added as grid: 

$ scp grid01:.ssh/authorized_keys .ssh/authorized_keys

Now do a cross login from every node to every other node (even to its self) to add all to the known_hosts. The installer needs this.

Storage tasks

Discover LUNs

# luxadm -e port | \
    nawk '{print $1}' | \
    xargs -n 1 luxadm -e dump_map | \
    nawk '/Disk device/{print $5}' | \
    sort -u | \
    xargs luxadm display | \
    nawk '

/Unformatted capacity:/{
  capacity=$(NF-1)""$NF;
}
disk != "" && /^$/{
  printf "%s vendor=%s serial=%s capacity=%s\n",disk,vendor,serial,capacity;
}' | \
    sort -u

Label Disks

Single Disk

# printf 'type 0 no no\nlabel 1 yes\npartition\n0 usr wm 8192 $\nlabel 1 yes\nquit\nquit\n' | \
    format -e /dev/rdsk/<disk>

All FC disks

For x86 you have to call format -> fdisk -> y for all disks first :-\

DON'T DO THE NEXT STEP IF YOU DO NOT KNOW WHAT YOU DO!

format_command_file.txt: 

type 0 no no
label 1 yes
partition
0 usr wm 8192 $
label 1 yes
quit
quit

# chown -RL grid:asmadmin /dev/rdsk/c0t6000*
# chmod 660 /dev/rdsk/c0t6000*


Set swap to physical RAM

# export RAM=256G
# swap -d /dev/zvol/dsk/rpool/swap
# zfs destroy rpool/swap
# zfs create \
   -V ${RAM} \
   -b 8k \
   -o primarycache=metadata \
   -o chksum=on \
   -o dedup=off \
   -o encryption=off \
   -o compression=off \
   rpool/swap
# swap -a /dev/zvol/dsk/rpool/swap


Network

Check port ranges

# for protocol in tcp udp ; do ipadm show-prop ${protocol} -p smallest_anon_port,largest_anon_port ; done
PROTO PROPERTY              PERM CURRENT      PERSISTENT   DEFAULT      POSSIBLE
tcp   smallest_anon_port    rw   9000         9000         32768        1024-65500
tcp   largest_anon_port     rw   65500        65500        65535        9000-65535
PROTO PROPERTY              PERM CURRENT      PERSISTENT   DEFAULT      POSSIBLE
udp   smallest_anon_port    rw   9000         9000         32768        1024-65500
udp   largest_anon_port     rw   65500        65500        65535        9000-65535

Setup private cluster interconnects

Example with a small net with six (eight with net and broadcast) usable IPs. This limits the maximum number of nodes to six... which is obvious...

First node: 

# ipadm create-ip net1
# ipadm create-addr -T static -a 10.65.0.1/29 net1/ci1
# ipadm create-ip net5
# ipadm create-addr -T static -a 10.65.0.9/29 net5/ci2

Second node: 

# ipadm create-ip net1
# ipadm create-addr -T static -a 10.65.0.2/29 net1/ci1
# ipadm create-ip net5
# ipadm create-addr -T static -a 10.65.0.10/29 net5/ci2

Set slew always for ntp

After configuring ntp set slew always to avoid time warps! 

# svccfg -s svc:/network/ntp:default setprop config/slew_always = true
# svcadm refresh svc:/network/ntp:default
# svccfg -s svc:/network/ntp:default listprop config/slew_always
config/slew_always boolean    true
