In section 5, We revealed you the way to identify all the SATP guidelines

I experienced to divide the screenshots into four quadrants with the intention that i really could reveal all contents with the production. Right here, i have attempted to cut it straight down and write only the lines I need to program. To do this, we used the following order:

This command details all SATP rules following makes use of grep for any string’s unit, satp_alua, and ---. This leads to the result getting line headers and separator contours, which are the very first two lines within the output. The remainder result series just the contours with satp_alua in them. Realize that the -i debate triggers grep to ignore the situation.

Within this productivity, observe that the EMC CLARiiON CX families is stated by VMW_SATP_ALUA_CX plug-in, centered on matches from the product column environment becoming DGC and declare Options position are tpgs_on.

Conversely, both LSI and IBM 2810-XIV is claimed because of the VMW_SATP_ALUA plug-in, according to fits on the merchant column, the Model line, and property value tpgs_on from inside the state Possibilities line.

NetApp can be claimed of the VMW_SATP_ALUA plug-in, predicated on fits regarding the provider line while the worth of tpgs_on within the Claim Alternatives column best. In this instance, the design column wasn’t used.

IBM DS8000, that’s model 2107-900 (listed in the productivity without rush), and IBM SVC (right here as product 2145) include said by the VMW_SATP_ALUA plug-in, on the basis of the provider and design columns only, even though the Claim Possibilities column setting isn’t tpgs_on.

The rest of the tip permits VMW_SATP_ALUA to claim gadgets with any supplier or unit column importance, so long as the Claim Possibilities column price was tpgs_on. This means any collection maybe not placed in the preceding formula that return a nonzero worth the TPGS industry inside inquiry feedback string will get reported by VMW_SATP_ALUA. You may think of this as a catch-all ALUA declare tip that claims products on all ALUA arrays that are not explicitly detailed by vendor or unit for the SATP state procedures.

Checking Units’ ALUA Designs

ALUA designs become associated with LUNs in conjunction with TPGs. To list these designs, you’ll be able to manage here demand:

This output reveals the storage space collection Type area set to VMW_SATP_ALUA_CX, the just like the VMW_SATP_ALUA plug-in with additional code to undertake some instructions certain to CLARiiON CX ALUA arrays.

The productivity also shows the storage space variety sort unit Config line, covered for readability, which include numerous portion:The earliest set of curly brackets, , includes initiator registrationa€“specific setting. This will be particular to EMC VNX while the CLARiiON group of arrays. In this set, two choices are indexed:

navireg=on-This means that NaviAgent enrollment option is enabled about this number. It registers the initiator making use of the VNX or CX selection if it's not already subscribed. Observe that you should check the initiator record about range to ensure that Failover means is set to 4, which makes it possible for ALUA because of this initiator. (available additional information about this in section 7.)

ipfilter=on-This option filters the number’s IP address so that it is perhaps not noticeable to the storing variety. (you will discover more about this in section 7.)

The ALUA AAS control function choices are enclosed in the second pair of curly brackets, within which will be another nested couple of curly brackets for any TPG’s AAS configuration. They are the ALUA AAS management setting options:

Explicit_allow=on-This means the number is actually set up to permit the SATP to work out the direct ALUA ability when the requirement occurs (eg, in case of an unsuccessful controller).
