In Chapter 5, We showed you how to identify all the SATP policies

I experienced to separated the screenshots into four quadrants making sure that i really could showcase all information from the production. Right here, i have made an effort to cut it lower and listing just the lines i have to showcase. To do this, I utilized the following command:

This command lists all SATP principles right after which makes use of grep for any string’s design, satp_alua, and ---. This leads to the production getting line headers and separator contours, which have been the first two lines within the output. The remainder result shows only the lines with satp_alua in them. Realize that the -i argument causes grep to disregard your situation.

Within this output, notice that the EMC CLARiiON CX family members are stated from the VMW_SATP_ALUA_CX plug-in, according to suits regarding product column setting becoming DGC therefore the declare Possibilities establishing becoming tpgs_on.

However, both LSI and IBM 2810-XIV include claimed because of the VMW_SATP_ALUA plug-in, centered on fits about Vendor column, the Model line, additionally the worth of tpgs_on into the state choices column.

NetApp can be stated by the VMW_SATP_ALUA plug-in, based on fits throughout the merchant line therefore the worth of tpgs_on in the state Possibilities line just. In cases like this, the unit column had not been used.

IBM match Promo kГіd DS8000, that will be design 2107-900 (listed in the productivity minus the dash), and IBM SVC (listed here as unit 2145) include reported because of the VMW_SATP_ALUA plug-in, in line with the Vendor and design articles best, although the Claim Solutions column style is certainly not tpgs_on.

The remaining tip permits VMW_SATP_ALUA to claim units with any merchant or product column price, so long as the Claim Options column value try tpgs_on. Which means that any selection perhaps not placed in the preceding guidelines that comes back a nonzero benefits for your TPGS area in inquiry feedback sequence will get reported by VMW_SATP_ALUA. You could think for this as a catch-all ALUA declare guideline that claims equipment on all ALUA arrays that aren’t clearly listed by merchant or design for the SATP declare formula.

Identifying Systems’ ALUA Configurations

ALUA configurations become related to LUNs in combination with TPGs. To record these configurations, it is possible to run the next demand:

A good example from an EMC VNX or CLARiiON CX range

This result shows the space variety kind area set-to VMW_SATP_ALUA_CX, which is the just like the VMW_SATP_ALUA plug-in with additional rule to carry out particular instructions certain to CLARiiON CX ALUA arrays.

The output also shows the Storage Array kind tool Config line, covered for readability, including many portion:The earliest set of curly brackets, , includes initiator registrationa€“specific arrangement. This is particular to EMC VNX additionally the CLARiiON group of arrays. Through this ready, two options are listed:

navireg=on-This means NaviAgent enrollment choice is allowed about this host. It registers the initiator making use of the VNX or CX array if it is not already registered. Note that you need to look into the initiator record throughout the array to ensure that Failover form is scheduled to 4, which makes it possible for ALUA with this initiator. (You can find more details about this in Chapter 7.)

ipfilter=on-This alternative filters the number’s internet protocol address which makes it perhaps not visible to the space collection. (you will find out about this in section 7.)

The ALUA AAS control function choices are enclosed in one minute set of curly brackets, within and that is another nested couple of curly brackets for the TPG’s AAS arrangement. These represent the ALUA AAS management means possibilities:

Explicit_allow=on-This means the host is designed to permit the SATP to exercise the explicit ALUA capability if require arises (for example, in the eventuality of a failed control).
