Functionality-wise, there are no configuration and troubleshooting differences to the end-user in IOS or IOx, with or without mSATA. The system simply recognizes the additional storage. There are some CLI commands that will show information that pertains to the mSATA storage. Examples are show inventory, and show platform msata.

Router#show platform hardware msata lifetime
SSD Lifetime Remaining: 99% -> 99% of the net disk read/write lifetime is remaining

Router#show platform hardware msata status
SSD is present

Router#show platform hardware msata

IOx Local Manager/ Fog Director can now display the wear leveling data for the mSATA SSD on the IR1101.

In the IOx Local Manager, it is observed by selecting System > Storage .

From the IOS command line, you can monitor the lifetime using the show platform hardware msata command.

Router#show platform hardware msata lifetime
SSD Lifetime remaining(%): 98

After a router reload, it will take a few minutes (approximately 5) before this data will be populated again.

When the SSD lifetime reduces to 15% and 5% of the lifetime limit, errors start getting reported in syslog.

For example:

*Jan 30 19:03:00.257: %IOX-4-IOX_SSD_LIFETIME_WARN: SSD Lifetime remaining in module:15
*Jan 30 19:02:30.157: %IOX-2-IOX_SSD_LIFETIME_CRITICAL: SSD Lifetime remaining in module:5

mSATA functionality was added to the router to add extra storage for IOx apps. The following table shows the router with the OID:

As part of this enhancement, SNMP support has been added for the following mSATA parameters on the router:

• lifetime remaining (wear leveling)

• memory usage for the mSATA SSD

The show platform hardware msata command gives information about this MIB.

Related documentation:

https://www.cisco.com/c/en/us/support/cloud-systems-management/iox/tsd-products-support-series-home.html

https://developer.cisco.com/docs/iox/

<OID> = STRING: "Lifetime Remaining: 99%, Usage: 30%"

The following conditions must be met before performing SNMP requests on the Router:

• An active mSATA module must be configured in the router.

• The Integrator must have incorporated the supported pluggable mSATA into their design.

• Verify this using the show platform hardware msata CLI.

• After a router reload it will take approximately 5 minutes before mSATA data will be populated again. Only SNMP get is allowed on the OID and is marked as read-only. Setting its value will not be allowed.

• Configurations to enable SNMP on the router are necessary for fetching MIB value.

YANG is a popular data modeling language to represent data sent over network management protocols such as NETCONF and RESTCONF. The Cisco-IOS-XE-device-hardware-oper YANG model has been modified to show mSATA information. mSATA has two CLIs to display associated data.

These two CLIs are:

show platform hardware msata status

• The CLI gives information on whether the SSD is present or not.

• If the SSD is present, a message "SSD is present" is displayed.

• If the SSD is not present, a message "SSD is not present" is displayed.

show platform hardware msata lifetime

• If SSD is present an output representing the SSD lifetime in % is displayed: "SSD lifetime remaining (%): 99"

• If SSD is not present, a message "SSD is not present" is displayed.

A typical YANG response for mSATA in device-inventory is as shown below:

 <device-inventory>
          <hw-type>hw-type-ssd</hw-type>
          <hw-dev-index>5</hw-dev-index>
          <version>V00</version>
          <part-number>IR-SSD-MSATA-100G</part-number>
          <serial-number>FOC21520XFV</serial-number>
          <hw-description>mSATA Module</hw-description>
          <dev-name>Expansion module 2 - mSATA Module</dev-name>
          <field-replaceable>true</field-replaceable>
          <hw-class>hw-class-virtual</hw-class>
          <lifetime>99</lifetime>
</device-inventory>

Cisco IOS-XE Yang Data Models are found here:

Each release has a directory, and the 17.5.1 release is found under 1751.

With previous software releases, the mSATA and Digital I/O on the IRM-1100-SPMI were only supported on the Expansion Module side of the IR1101. With 17.8.1, support is available on the Compute Module (CM) side with the following restrictions:

IRM-1100-SPMI installed on both sides:

• This combination is not supported.

• Only the mSATA and Digital I/O from the EM side will work.

• The Digital I/O from the CM side will NOT work.

IRM-1100-SPMI installed on the CM side:

• The mSATA and Digital I/O will work.

• The Digital I/O instances will be numbered 1-4.

You can set the alarm severity to critical, major, minor, or none. The severity is included in the alarm message when the alarm is triggered.

To configure and show alarms on the IR1101, use the Command Line Interface (CLI).

Router(config)#alarm contact ?
<0-4> Alarm contact number (0: Alarm port, 1-4: Digital I/O)

Release 17.7.1 will add support for the following SFPs:
