changing a hdd FOR A hpe 3PAR STOREVIRTUAL

by Samuel Mitchell, posted in Data Center Virtualization, HP

I have gotten a case to change a failed hard drive in a HPE 3PAR StoreVirtual 7200 storage system.

The process is not as simple as hot-swapping the hard drive which is possible but there are checks that have to be perform before this task is done to maintain the integrity of the data on the storage.

Before I go into the details, let me share how the 3PAR work. It is important to note that this system is different in how it stores data on the disk.

The 3PAR stores data in small chucks called chunklet which is spread across multiple drives using parity.

When the system detects a possible failure, the servicemag start to migrate all the data chunklets to other drives to mitigate against lost of data.

This functionality takes me to the point that before you can replace a hard drive, it is important that you check the status of the servicemag to ensure the migration process is completed before removing the hard drive from the system. This crucial step will ensure data integrity and consistence across the drives.

To check if the migration of data hsa been completed, run the following command:

servicemag status

If the status indicate completed, then you are clear to replace the hard drive. Otherwise, you will have to wait for the process to complete which can be hours or days. The waiting period is dependent on the amount of data stored on the disk.

After the Hard Drive has been replaced, it does not stop there. You have to rerun the command below:

servicemag status

Common Switch Commands for the HP FlexNetwork

by Samuel Mitchell, posted in HP, Routing & Switching, Uncategorized

I have recently had to interact with an HP FlexNetwork 5510 switches and the command syntax was totally different from the HP-Aruba 2530. This article is to document the common switch commands that I use on a daily basis.

  • Show (Display) the list of interfaces and their status

display interfaces brief

  • list the directly connected devices using LLDP

display lldp neighbor-information list

  • Enter enable mode or exec privilege mode

system-view

  • Save switch startup configuration

write

  • Show the running configuration

display current-configuration

  • Configure IP helper on an interface

interface [interface_type]

dhcp select relay

dhcp relay server-address [dhcp_ip_address]

  • Configure NTP Service

ntp-service enable
ntp-service unicast-server 10.71.152.229
ntp-service unicast-server 10.220.0.35

  • Configure SSH

ssh server enable

ssh client source interface [interface]

service-type ssh terminal

  • Configure the default gateway

ip route-static 0.0.0.0 [gateway_ipaddress]

  • Configure interface as layer 2

port link-mode bridge

  • Configure interface as layer 3

port link-mode route

  •  Configure the interface as a trunk

port link-type trunk

port trunk permit vlan [vlan-id]

  • Configure the local user account to manage the switch

local-user [username] class manage
password simple [password]
service-type [options: ssh telnet terminal]
authorization-attribute user-role [role-name]

I will be adding more command as time goes by and I get familiar with the CLI.

Securing the Web management for the HP 2530 switch

by Samuel Mitchell, posted in HP, Routing & Switching, Security

Whenever you get a HP/Aruba 2530 switch out of the box, it comes default with web management enabled using http. You can easily go to the IP address of the switch to view the switch details. To secure the web portal of the switch, do the following:

  1. Log into the switch
  2. Go into configuration mode
  3. Create a self-signed certificate for secure http access

    1. crypto pki enroll-self-signed certificate-name [SWITCHNAME] subject

    2. Enter each information requested
  4. To enable secure http, use command

    1. web-management ssl

  5. To disable http for web management, use command
    1. no web-management plaintext
  6. To added a login for the web portal, use the command:

    1. password manager user-name [loginname] plaintext [loginpassword]

I hope this was useful.

Configuring similar Cisco features on an HP 2530 switch

by Samuel Mitchell, posted in HP, Routing & Switching, Uncategorized

I had the privilege to learn another vendor’s switch configure from HP. This article will be about Configuring the following parameters in a HP 2530 similar what you will do in a Cisco access switch:

  • Access port (edge port)
  • Trunk ports (tagged port)
  • Port security (MAC security)
  • Ether channel  (LAG)
  • Spanning tree
  • Portfast
  • Enable secret password
  • SNMP
  • Switch virtual Interface  (SVI)
  • Vlan default gateway
  • Show logging on the console

Before I begin we need to know that there are two main standards in the networking world, it is either Cisco or IEEE. So vendors like HP will only follow the IEEE standards. With that being said, let us begin:

What I am going to do is to show the Cisco way of the commands for the particular feature followed by HP.

1. Trunk ports: we know that Cisco switch has two protocol Used to develop a trunk port; ISL and 802.1Q (IEEE standard). Although the newest Cisco are no longer supporting ISL as it is being faced outed.

CISCO: 

SW(config-if)# switchport trunk encapsulation dot1q

SW(config-if)# switchport mode trunk
SW(config-if)# switchport trunk allow vlan 1-5
SW(config-if)# switchport trunk native vlan 5

HP:

SW(configure)# int 49

SW(eth-49)# tagged vlan 1-4

SW (eth-49)# untagged vlan 5

 

2. Creating and configuring Voice vlan on a switch port that tells the IP Phone which vlan to use for communication.

CISCO:

SW(config)# interface f0/1

SW(config-if)# switchport voice vlan 6

HP:

SW(configure)# vlan 6

SW(vlan-6)#voice

SW(configure)#int 1

SW(eth-1)#tagged vlan 6

 

3. Configure Spanning-tree portfast to let the port transition into forwarding state immediately and also this configures the port as a access/edge port.

CISCO:

SW(config)# interface Fa0/1

SW(config-if)# switchport mode access

SW(config-if)# switchport access vlan 2

SW(config-if)# spanning-tree portfast

HP:

SW(configure)# spanning-tree 1 admin-edge-port

SW(configure)# interface 1

SW(eth-1)# untagged vlan 2

 

4.  Configure BPDU Guard to prevent a switch from connecting to a access port by shutting it down.

CISCO:

SW(config)#interface range fa0/1 – 24

SW(config-if-range)#spanning-tree bpduguard enable

HP:

SW(configure)# spanning-tree 1-24 bpdu-protection

 

5. Configure RSTP protocol to prevent loops in a network.

CISCO:

SW(config)# spanning-tree mode rapid-pvst

HP:

SW(configure)# spanning-tree

SW(configure)# spanning-tree force-version rstp-operation

 

6.  Configure Port security using mac address restriction and limiting the number of devices connected.

CISCO:

SW(config)# interface range f0/1 – 24

SW(config-if-range)# switchport port-security

SW(config-if-range)# switchport port-security maximum 2

SW(config-if-range)# switchport port-security violation restrict

HP:

SW(configure)# port-security 1-24 learn-mode limited-continuous address-limit 2

 

7. Configuring SNMP on the switch for monitoring tool to access the switch status.

CISCO:

SW(config)# snmp-server community [string-password] ro

HP:

SW(configure)# no snmp-server community public

SW(configure)# snmp-server community [string-password] restricted

 

8. Configure username and password on the switch.

CISCO:

SW(config)# username admin privilege 15 secret [password]

HP:

SW(configure)# password manager user-name [admin] plaintext [networkpassword]

 

9. Configure Etherchannel or Link Aggregation (LAG) port to bundle two or more ports together. Remember that LACP is the standard protocol for other vendors except Cisco.

CISCO:

SW(config)# interface range Fa0/47 – 48

SW(config-if-range)#channel-protocol lacp

SW(config-if-range)# channel-group 1 mode active

HP:

SW(configure)# trunk 47-48 trk1 LACP

 

10. Configure Switch Virtual Interface IP address and default gateway.

CISCO:

SW(config)# ip default-gateway 10.1.1.1

SW(config)# int vlan 1

SW(config-if)# ip address 10.1.1.10 255.255.255.0

SW(config-if)# no shutdown

HP:

SW(config)# ip default-gateway 10.1.1.1

SW(config)#int vlan 1

SW(vlan-1)#ip address 10.1.1.10 255.255.255.0

 

11. Show logging on the console

Cisco:

SW(config)# terminal monitor

HP:

SW# debug destination session

SW# debug event
