Linux: How to check CPU Count & Memory

// memory Utilization
[root@host ~]# free -m
             total       used       free     shared    buffers     cached
Mem:        258294       2802     255492          0        187        735
-/+ buffers/cache:       1879     256414
Swap:        16499          0      16499

// CPU Processor Count
[root@ahost ~]# nproc
32
(if the above didn't work, try the below 2 cmds for CPU Count & no of Cores)
[root@host ~]# grep -c processor /proc/cpuinfo
8
[root@host ~]# grep "cpu cores" /proc/cpuinfo |sort -u |cut -d":" -f2 | awk '{s+=$1} END {print s}'
4
// the below cmd give detail CPU info
>>less /proc/cpuinfo

Sym Authorization Check

1. symcli cmd to check the list of users and their access

D:\Program Files (x86)\EMC\SYMCLI\bin>symauth -sid <SymmID> -users list

   S Y M M E T R I X   A U T H O R I Z A T I O N   U S E R S

Symmetrix ID: 000XXXXXXXXX

                                                                           Flags
Role              User/Group name                Component                   E
---------------   -----------------------------  ------------------------- -----
Admin             User  D:Domain1\User 1           N/A                         .
Admin             User  D:Domain2\User2          N/A                    


2. How to add user in symcli.

   .D:\Program Files (x86)\EMC\SYMCLI\bin>symauth -sid <SymmID> -f c:/access.txt commit -nop

access.txt
assign user D:Domain1\User1 to role admin;
(or for group)
assign group D:Domain1\User1 to role admin;

3. How to remove User Access using symcli

   .D:\Program Files (x86)\EMC\SYMCLI\bin>symauth -sid <SymmID> -f c:/access.txt commit -nop

access.txt
delete User/Group D:Domain1\User1;

D:Domain1\User1 - you actually cross verify the user name as it in box, using CMD symauth -sid <SymmID> -users list
