Blog @ E-knows.net

I haven’t updated this blog lately. It’s been almost 3 months since the last entry. What had happened in the past 3 months? Personally, I am happy with my current job though it can be taxing at some time when I was on call for that particular week. On positive note, at least this is far better that my previous employment where I was on call 24×7x365.

Good news is that I know that I will be a dad next year.

On my technical learning and development, I have not studied for any IT certification for the past 3 months. Getting a cert in Netapp or any storage certification will be my target for next 1 year. All my Juniper certifications have expired and I do not have any plan to renew them since I am not working with routers and switches recently and maybe I do not have plan to jump into networking field anytime soon.

This is taken directly from Netapp Now website. Really useful for Netapp Administrator

How to locate a failed disk drive using disk LEDs

How to locate a failed disk drive using disk LEDs
Keywords : blink, flash, drive, shelf slot
Cause of this problem
Disk failed and red LED is not automatically illuminating.
Solution
To physically locate a disk using the disk’s LED, follow these steps. You may substitute ‘blink_on’ and ‘blink_off’ with ‘led_on’ and ‘led_off’.
To enable and disable disk LED blinking (this example uses disk 0a.19):
1. Access advanced commands:
For Data ONTAP 6.0 and later, type: priv set advanced
For earlier releases, type: rc_toggle_basic
2. To enable LED blinking:
blink_on 0a.19
The left LED on the disk will start blinking.

Note: If this is being used for MetroCluster, use the disk name and disk ID. For example:
blink_on :
3. To disable LED blinking:
blink_off 0a.19
The left LED on the disk will stop blinking.
4. Exit advanced commands:
For Data ONTAP 6.0 and later, type: priv set
For earlier releases, type: rc_toggle_basic
If the disk is broken and the red LED does not illuminate, turn on the disk LEDs adjacent to the defective disk. For example, if disk 4.19 fails and its red LED does not turn on, enter the following series of commands:
1. Access advanced commands:
For Data ONTAP 6.0 and later, type: priv set advanced
For earlier releases, type: rc_toggle_basic
2. Turn on the LEDs adjacent to the failed disk:
led_on 0a.18
led_on 0a.20
Disks 0a.18 and 0a.20 LEDs will be illuminated.
3. Turn off LEDs:
led_off 0a.18
led_off 0a.20
4. Exit advanced commands:
For Data ONTAP 6.0 and later, type: priv set
For earlier releases, type: rc_toggle_basic
• Note:
For Data ONTAP GX, you can enter the following command to cause the led on the left side of the drive to illuminate amber:

storage disk setled -disk -action on
If the disk is failed to the point that the led will not illuminate, turn on the LEDs to the disks adjacent to the one reporting this error.
The following are other useful commands to locate disks:
• To find the position of disks, type: fcstat device_map
• To list spare disks, type: vol status -s
• To list broken disks, type: vol status -f
Refer to Remove failed disks quickly from NetApp Best Practices for Reliability and to the respective hardware and service guidefor each storage appliance.
Note: For disks in a Fibre Channel fabric, the FC switch name is case sensitive. If the ’sysconfig -a’ shows the disk ID as “KHHQ-R-SW02BSW2:7.20″, the command would be:
blink_on KHHQ-R-SW02BSW2:7.20
Not:
blink_on
khhq-r-sw02bsw2:7.20

For those who signed up for Microsoft Beta exam testing, you should probably got the beta code for the registration.

Registration begins: May 17, 2010, 12 AM Eastern Standard Time (What time is this in my region?)

Beta exam period runs: May 21, 2010–June 11, 2010

Ontap Simulator version has been release for quite a while. I will need to set up the test environment with the new Ontap 8.0 because my company is starting to migrate to Ontap 8. The good news with Ontap 8 is it now supporting 64-bit aggregate in which means more storage for my customers.

To download this simulator, you just need to go the now.netapp.com , make sure you are the existing customer/reseller for the access.

Ndmpcopy: 10.10.xx.xx: Log: RESTORE: cannot reserve blocks for file ./windows_10: Operation not permitted.

You received this error while you are trying to ndmpdcopy from one Netapp storage filer to another Netapp storage filer. This error is caused by insufficient space on the destination filer that you wanted to copy.

To solve this problem, increase the volume size in the destination filer to the appropriate size.

vol size <vol_name> +100g
