Virtual Disk commands using RACADM
Hi,
We wish to interrogate our fleet (Several generations of servers and controllers, including R730XDs) for their Storage Read and Write Policies.
We want to be able to change those policies if they do not meet our criteria.
I cannot find the specific RACADM commands to do the above. I have downloaded the paper RAID And Storage Configuration using RACADM Commands in iDRAC7, but cannot see the correct commands to use.
Can someone pls point me to the correct commands, starting with the interrogation command to see the status of the Read and Write Policies?
Thx for your help,
John Bradshaw

racadm storage get vdisks -o
or
racadm storage get vdisks -o -p DiskCachePolicy
The -p property subcommand will reduce the amount of information provided and only list the value specified.
The command to change the policy would be something like this:
racadm set Storage.VirtualDisk.DiskCachePolicy.7 disabled
Some of these commands are case sensitive, so it is best practice to use proper case. Virtual disk numbering starts at 0, but the command arguments start at 1. Virtual disk 6 would correlate to 7.
Thanks

Hello
I'm not sure about a RACADM command. If you really need a RACADM let me know and I will see if one exists. You should be able to accomplish this using omreport and omconfig commands. The disk cache policy is set at a virtual disk level on most of our controllers. If you have a controller that allows non-RAID or HBA mode then it will be set at a physical disk level. The command to get the disk information would on vdisks or pdisks would be:
omreport storage vdisk controller=0
omreport storage pdisk controller=0
You can configure the cache policy with omconfig commands.
omconfig storage vdisk controller=0 vdisk=6 action=changepolicy diskcachepolicy=enabled
The command should be very similar when changing pdisk policy on an HBA controller.
Thanks

Hi again Daniel,
Racadm storage get vdisks -o gets us out of trouble.
Thx,
