A flash reporting a possible issue that could occur if a drive fails during drive firmware update can be found here.

Until the flash is updated showing how to avoid this issue, only update drive firmware when installing a new machine or if all hosts are offline.

IBM recently released new drive firmware for the Storwize V7000, so I thought I would share the process of how I update that firmware. You can download it from here. The details for this new package can be found here. I recommend you perform the drive update before you next update your Storwize V7000 microcode.

I want to be clear that one of the central goals of the Storwize V7000 is to ensure that performing drive firmware updates can be done online without host disruption. This is possible because each drive can be updated in less than around 4 seconds. The scripts I share below leave a 10 second delay between drives just to be safe. I would still prefer that you did the update during a quiet period.

We need to perform this procedure using the command line as there is no way to do this procedure from the GUI (yet).

There are four steps:

Upload the Software Upgrade Test Utility to determine which drives need updating.

Upload the drive microcode package.

Apply the drive software.

Confirm all drives are updated.

Step 1: Upload and run the upgrade utility

You will need the upgrade test utility which you can get from here.

You will need the Putty utility PSCP which you can get from here (although most of you should already have it).

You will need to have created a public/private key pair and assigned it to a user. In all the examples the user name I use is anthonyv. You need to use your own user-id, although you could also use admin. The process to create and associate the key pair is described here. Place the PPK file into the putty folder along with the upgrade test utility.

From the Putty folder we need to upload the test utility. You will need to change the key file name, userid and IP address (all highlighted in red) to suit your installation.

NOTE: The following command is being run in a Windows command prompt. You need to be in the C:\Program Files\Putty or C:\Program Files (x86)\Putty folder.

pscp -i anthonyv.ppk IBM2076_INSTALL_upgradetest_6.15 This email address is being protected from spambots. You need JavaScript enabled to view it.:/home/admin/upgrade

Having uploaded the file, now start PuTTY and SSH to your Storwize V7000. Logon and issue the following two commands. You are using SSH commands now, not the Windows Command Prompt:

svcservicetask applysoftware -file IBM2076_INSTALL_upgradetest_6.15 svcupgradetest -f -d

If you get a warning window like the one shown below, indicating we have down-level drives, we need to proceed to the next step (note that the enclosure and slot numbers are not the same as drive IDs). If you have a lot of drives, you can drop the -d from the svcupgradetest command to get a summary list.

Step 2: Upload the drive microcode package

Download the drive update package from here. Put it into the PuTTY folder.
From a Windows command prompt we need to upload the package using the following command. You will need to change the key file name, userid and IP address (all highlighted in red) to suit your installation. Note yet again that you are running this in a Windows command prompt from the PuTTY folder (not from inside an SSH session):

pscp -i anthonyv.ppk IBM2076_DRIVE_20110928 This email address is being protected from spambots. You need JavaScript enabled to view it.:/home/admin/upgrade

Step 3: Apply the drive software

I have written some scripts to help you list the drive IDs that need to be updated and perform the updates. You can upgrade the drives one at a time, or in bulk, depending on how you want to do this. All the remaining commands are all run in a PuTTY session.

Firstly run this script to list all the drive IDs and current firmware levels. We need the drive IDs if we want to update individual drives.

svcinfo lsdrive -nohdr |while read did error use;do svcinfo lsdrive $did |while read id value;do if [[ $id == "firmware_level" ]];then echo $did" "$value;fi;done;done

The output will look something like this, showing the drive ID and that drive's current firmware level. From step 1 we know what the latest firmware level is, so we can compare to the current firmware level:

0 291E 1 291E 2 B546 3 B546 4 B546 5 B546 6 B546 7 B546 8 B546 9 B546 10 B546 11 B546 12 B546 13 B546 14 B546 15 B546 16 B546 17 B546 18 B546 19 B546 20 B546 21 B546 22 B546 23 B546

Now we can update individual drives with this command, which will update drive ID 23. Just keep changing the drive IDs, using the list of down-level drives, until every drive has been updated:

svctask applydrivesoftware -file IBM2076_DRIVE_20110928 -type firmware -drive 23

However you may have a lot of drives and want to upgrade them in bulk. So you could use this command, which updates drive ID 19 and 20 (highlighted in red). You could change and also add extra drives to the list as required:

for did in 19 20;do echo "Updating drive "$did;svctask applydrivesoftware -file IBM2076_DRIVE_20110928 -type firmware -drive $did;sleep 10s;done

If we just wanted to upgrade every single drive in the machine (regardless of their level), we could run this command:

svcinfo lsdrive -nohdr |while read did name IO_group_id;do echo "Updating drive "$did;svctask applydrivesoftware -file IBM2076_DRIVE_20110928 -type firmware -drive $did;sleep 10s;done

When updating multiple drives, I have inserted a 10 second sleep between updates, just to ensure the process runs smoothly. This means each drive takes about 13-15 seconds.

Once we have upgraded every drive, it is time for a final check.

Step 4: Confirm all drives are updated

You have two ways to confirm this. Firstly run the following command to list the firmware level of each drive. Is each drive reflecting the levels reported in Step 1?

svcinfo lsdrive -nohdr |while read did error use;do svcinfo lsdrive $did |while read id value;do if [[ $id == "firmware_level" ]];then echo $did" "$value;fi;done;done

Now run the software upgrade test utility again:

svcupgradetest -f -d

Provided you receive no warnings about drives not being at the recommended levels, you are now finished with the drive updates. Of course you could now proceed to install 6.2.0.4 firmware, but you can do that from the GUI.
