EMC testing consists of 4 main items:1. ESDUsing electrostatic gun test, contact voltage ±6kv, the whole box and the internal visible metal parts are detected;Air discharge positive and negative 8KV, detection of the box and the internal metal parts (such as Board jam body), the special detection of 220V power Plug and switch place.Note: The contact discharge and air discharge test is different from the electrostatic gun tip, contact discharge tip for
name of the string, the name of the identifier. The way to create a Symbol object is to precede the name or string with a colon:Create a Symbol object, for example:: Foo:test: "ABC" #结果是: "I am a Boy"String is a string, why do you have the name of the string? This is because a string is also an object in Ruby, a string object. Both the structure and the operation and the Symbol object are different.7, in Ruby each object has a unique object identifier (Identifier), you can use the Object_ID met

A m*n/b
B N*log (m/b)
C m*n/(2b)
D (m+n)/b
E log (m*n)/b
Which of the following descriptions of Reader/writer locks are/is wrong?
A caller cannot upgrade its read lock (already obtained) to write lock
B caller can downgrade its write lock (already obtained) to read lock
C caller can get read lock if there is no write lock
Failure phenomenon:
If it's leovo|, How should EMC storage and hard disk configuration be configured? What's the note?
Solution:
Please refer to the following instructions:
1, VNX series of storage before the four disk is the system disk, the system will occupy the first four disk per 194GB of capacity, in the VNX2 generation storage, the system capacity accounted for 300GB, this part of the capacity for the user is not available;

find the maximum radiation value;c) Substitution method: The use of ERP (effective transmitting power) to replace, and then converted into field strength values. This is often used in RF testing and is rarely used by conventional EMC. The purpose of the substitution test is to test the radiation of the eut shell, requiring the removal of all detachable cables and the use of a ferrite ring on a non-detachable cable. First, the maximum disturbance valu

Back up all data on the local disk to tapeBy default, you do not need to specify the file system device number. The value is "/dev/RMT/0 m ". However, if this device does not contain tape media or you need to apply other devices, you must add the
This time the operation is to increase the NAS space:Do not add a new path, only increase the capacity of one tree, it is relatively simple, do not want to do on backup, if you add a new tree, you need to modify the DataList backup script.The steps
Host disk configuration:Create a volume group, create a logic volume, and add physical volume to the logical volume.
Is the disk array space identified. Create a file system, that is, format it, usually JFS or jfs2. Mount the created File System
