HP StoreAll OS 6.5.1 Upgrade Guide

Table 1 Prerequisites checklist for the StoreAll upgrade
Step
completed?DescriptionStep
Verify if password-less access is configured on the cluster nodes. Run the following command
from each StoreAll node:
pdsh -a date
1
The command output should display the date from each node in the cluster, which means
password-less access is configured.
If the command output displays an error for any node, enable password-less access on all
cluster nodes before starting the upgrade. The following example procedure uses a two
node cluster with servers fsn1 and fsn2.
1. Check that the file/etc/machines file exists on each node and has an entry for
each server in the cluster. Example entry:
cat/etc/machines
fsn1
fsn2
2. Log in as root. In the command prompt, run ssh-keygen.
3. Follow the prompts. Do not choose a passphrase.
Example session:
ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key:
/root/.ssh/id_rsa
Created directory '/root/.ssh'.
Enter passphrase:
<empty_no_passphrase>
Enter same passphrase again:
<empty_no_passphrase>
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
c4:51:ee:96:9c:c2:52:0b:31:20:4f:73:3f:4e:c1:f4 root@ibrix01
4. Copy the key to all nodes in the cluster. You will be prompted for the root password
each time.
Example session for fsn1:
ssh-copy-id -i /root/.ssh/id_rsa.pub fsn1
21
The authenticity of host 'fsn1 10.0.0.21)' can't be established.
RSA key fingerprint is d3:ba:85:98:58:a2:c6:35:e5:6c:62:ae:d8:bd:47:84.
Are you sure you want to continue connecting (yes/no)?
yes
Warning: Permanently added 'fsn1,10.0.0.21' (RSA) to the list of known
hosts.
root@fsn1's password:
5. Log in to fsn1 using ssh fsn1.
6. Confirm that there are no extra or unwanted keys in the file .ssh/authorized_keys.
7. Open the etc/ssh/sshd_config file on the server you are running the upgrade
from and record the value of MaxStartups. You will use this value in the next step.
8. Confirm that password-less access has been successfully configured.
pdsh -f <MaxStartupValue> -a date
If the password-less access has been successfully configured, the command output will
display the date from each node in the cluster.
Example with a MaxStartups value of 2:
pdsh -f 2 –a date
fsn1: Tue Mar 25 10:47:12 EDT 2014
fsn2: Tue Mar 25 10:47:12 EDT 2014
Verify, for the entire cluster, what version of StoreAll OS is currently running by entering
the following command:
ibrix_version -l
2
