Assign S/N to parts

[xwcwt]

This info copy from ZB written by Dr.Li:

The ID of the parts are assign in the following policy:

An ID for example: SFP20100401

1. The first three digits "SFP" denotes that this part is brought from the market individually.
"SFCB" denotes the part comes from other devices (e.g. the memory modules from a server).
"SFCB" also may indicate that these parts are not for our company. For example, we may borrow some parts from other companies.
SFS denotes it's a Server and SFC says it's a cluster.

2. The next 4 digits denotes the year we got these parts.

3. Then, there are 2 digits indicating the batch we brought these parts. Same parts brought together shares the same batch number. For assigning a batch number, you can find the minimum number not currently used simply by sorting the table with the serial number

4. The last 2 digits indicates the part number in the batch.
In case the last 2 digits are not sufficient for a batch with more than 100 parts, you may create new batch number.
Hopefully, we may not issue 100 batches of purchases during one year.

5. for HD's serial number, our serial number is <prefix> + <hd item's serial number>. Example: say WDS05FN is the SN of one HD and the ID according our rule is SFP20150203, then it will be SFP20150203WDS05FN.

Then, now you may all understand these s/n.

20170516/cwt: remove the HD's special rule.

for HD's serial number, our serial number is <prefix> + <hd item's serial number>

For making it easy to understand, could you give an example?

In my own thought the easiest way is combining current ID with HD serial number, say WDS05FN is the SN of one HD and the ID according our rule is SFP20150203, then it will be SFP20150203WDS05FN. Maybe a little 'long', as internal records I think we can accept.

Sounds good to me.

Merged into head-post.

5. An optional string can be added following the the 2-digit part number.
- for HD's serial number, our serial number is <prefix> + the string is <hd item's serial number>. Example: say WDS05FN is the SN of one HD and the ID segments for the above 1-4 section according to our rule is SFP20150203, then it's ID will be SFP20150203WDS05FN.

I suggest making the latest added string an optional component of the ID. So we may do this too for other kinds of parts. Changes are marked above.

@xwcwt: pls review and merge if it is good.

After discussed with Xinjie and Dr.Gu, we think there's need to attach the label into some important&easy attached parts such as Hard Disk. Also, there's an easy way to record many disks in nodelist system if the part ID is same. then I think there's no need to add <hd item's serial number> into HDs' part ID because it will make the record process too heavy.

@zma, @Xinjie.

Good to me. Let us wait for Zhiqiang's opinion.
